What are you talking about? If you ban people from selling their business they will just shut it down if they don't want to continue. Who is better off from that?
Or you have to force people to continue with their businesses, which is akin to trying to force an artist or athlete to continue to be at top level. You can't force that, no matter how many hackers agree with you.
this is a terrible argument.
Some people sell their kidneys. Some people sold their own children. Some people even sold themselves into slavery. Who are you to judge?
