It will also be a blow to the businesses. People will boycott those businesses they feel are discriminatory. There is plenty of precedent for this and often corporations have had to back down.

I once was involved with a city park that was created for the Boy Scouts but later turned over to the city. While I was there the Boy Scouts were banned from receiving financial aid from the city and people took a dim view of them when they used the park. The Girl Scouts, however, got a grant to use the park for weeks (This was the only city park in the country where there were cabins, bathrooms with showers, Fire pits, a climbing rock and a lot of other state park amenities). I think the Boy Scout acceptance of gays is a response to amend their discriminatory practices. But they still don't acknowledge of atheists, though.
