Well looking from the outside inwards as a complete outsider can, I'd say that that 'preamble' was a race-horse that fell at the gates and has gone nowhere ever since in relation to the United States of Absurdity these days.
The U.S. of Absurdity claims to be the Shining Light of Democracy, etc, etc, for the entire world BUT, in fact and the truths of Reality it has shown itself to be little more than the guttering flame of a match in the darkness.
Let us take a GOOD look at a few points here,
"In Order to form a more perfect Union......so on and so forth,"
Question #1 WHAT Perfect Union truly exists in the U.S.?
Question #2 WHAT REAL and Tangible JUSTICE exists in the U.S.?
Question #3 What REAL Domestic Tranquility TRULY exist within the U.S.?
Question #4 In what context is this "Common Defence" applied when the rest of the world view the U.S. as a Posse riding in and trying to FORCE its ideologies, etc, upon those who want to live THEIR own and have their Ideas?
Question #5 What "General Welfare" is there when ONLY those can truly afford it actually get it?
Question #6 " Liberty and Prosperity," for whom?
Imo, the U.S. of Absurdity has a system of Government that works ONLY for those who can reap the benefits of it for themselves and themselves ALONE.
Any TRULY Democratic form of Government MUST be based solely upon the following Tenets, i.e. A Government OF the PEOPLE, For the People and BY the People, should that NOT be so?

To bond people by making sure everybody plays by the same rules.
To protect us from sociopaths, criminals and foreign Invaders.
To pool our resources to guarantee education, health care, and other essential services.
To keep our water and air clean, our drugs, food and workplaces (among other things) safe.
Provide lots of other miscellaneous things we all take for granted. The list is an extensive one.
(Libertarians are either naive, insane, or predatory a-holes, btw.)

Exactly what the preamble says: impart justice, insure domestic tranquillity, provide for the common defense, promote the general welfare, and secure liberty to ourselves and our future generations.

We live in a world that the authors of the Constitution could hardly have imagined. The Constitution and Bill of Rights go only so far. Laws, judicial rulings, and administrative regulations have evolved, imperfectly, to keep pace with the changes in society.

Giant corporations wield more power than many nations do, and they do so in their own narrow interests, which often run counter to the health, safety, and long-term interests of society as a whole. Government is the only entity with enough power to regulate these behemoth corporations and prevent them from causing damage to society and the environment. One of the greatest problems in the U.S. today is the control (you might say stranglehold) that private, wealthy interests have on the government that is supposed to be regulating them.

I would like to add to these good comments. Government should provide balance between the other powerful force: Big Business. Our capitalistic country is a balance between government and big money.When we are out of balance, we are in trouble. When big business gets out of hand bad things happen. So regulations are needed. That's tricky because the economy is affected when the balance is upset.

While we're at it It would like to address another issue that so many people are not aware of: our food.
I remember when there was a shift in farming. Big business came in and overtook the farming industry ousting the smaller family farms. Then food production became prey to cheaper, unhealthy technology...
more pesticides, farm animals becoming things instead of living creatures...being made sick, tortured, gaseous and detrimental to our environment. Then there came too many processed food companies competing for our dollars. AND THEN CAME MONSANTO the masters of pesticides...fooling us by claiming that they had science on their side with those GMO's that create seeds that absorb lots of GLYPHOSATE to once and for all kill bugs and weeds...giving us now super bugs and super weeds and lots and lots of CANCER. If the workers in the fields get cancer from dealing closely with this, what do you think happens to us over time eating this abomination? This is not science; this is technology...bad technology, dangerous technology...and our people in government are fooled by them. Bill Gates says this is the answer to world hunger. He is in bed with Monsanto. Monsanto destroyed the agriculture on Paraguay, farmers in India had an epidemic of farmer's suicides due to Monsanto's bullying. There are countries that have outlawed Monsanto. Monsanto has been sued and fined millions due to their weed killing product, ROUNDUP, but you still see it on the shelves in stores and they advertise it on TV. It causes cancer. Monsanto is very rich. I only buy organic food and will not eat in a restaurant unless the food is organic. That is not easy. As far as it being more expensive, I would rather eat less and stay healthy. Socially, it creates a problem. But that's the price I pay to stay healthy. In the meantime, our government supports Monsanto and now Biden has appointed the wrong man to be Secretary of Agriculture. I love Biden, but he is not perfect and is naive about all of this as are the majority. If you research this bear in mind that it is rampant that big companies dummy up research findings. They lie for the dollar. But those court cases where people are awarded millions...that doesn't lie.

First, there should not be so many road blocks for people to qualify for healthcare, education, good infrastructure and justice...which needs to be handled by a government. Farming these things out to ‘for profit’ individuals and cooperations will not support a fair and balanced society! Providing decent healthcare, basic education and keeping infrastructure in good working order and not having a militarized justice system, should all be simplified to a basic application. All the different angles to laws and regulations has not given us more security, safety or happiness...at least not by the millions of guns this one Country owns for protection, by it’s citizens!

It seems that we have become more barbaric, than the advanced civilization, that we are touting ourselves to be!

Article I, Section 8 defines the powers of the Congress and thus the role of the government.

I will quote Lincoln here:

"The legitimate object of government, is to do for a community of people, whatever they need to have done, but can not do, at all, or can not, so well do, for themselves—in their separate, and individual capacities."
