The Best Solution to Racist (Homophobic, etc.) Businesses Who Refuse to Serve Certain Groups?

How 'bout we make it easier for folks to start a business so that they can take advantage of what would be an obvious money-making opportunity (blacks and gays use the same money as the rest of us, no?) and NOT leave it up to the cronies in government, the pre-existing businesses that don't want the competition and who lobby for something referred to as "certificates of necessity", etc.? I mean, I know that the left would much prefer to hold a gun to somebody's head and make them serve these folks (you know, that whole, "make the lesbian couple a cake or go to prison", mentality) but if we can achieve the same end without coercion, why pray tell wouldn't we?........................................................................................................P.S. And, besides, what are the odds that every single business would refuse to service an entire group, essentially flushing money down the toilet? It makes no sense.
