> The great thing about this, is that someone else will realize there is now an under-served market, and create a business to fulfill that need.

Except that every other business can now refuse to serve that business services, because that business serves people nobody else likes.

Given even time and systematic discrimination, that business owner and everyone they serve will be driven to destitution and cease to be a meaningful market segment. They, along with the people they serve can't afford to buy anything anyways.

Should society should just let them die because of the magic of capitalism and (???) rights?
