Nope, because then you have people saying “I won’t sell to blacks, if you force me sell them things I made it’s slavery”. And they aren’t being forced to work, they are being forced to operate under the parameters our society agreed to (via lawmaking). The baker can quit, he’s not forced to work there. The shop owner can close up shop, he’s not forced to run that business. But if the owner wants to run that business they have to follow the laws of the land which say you will serve the public, and that means all of the public.
