I have a simpler explanation, what likely happens is that most people don't even try to do it (even though they could do so like the case here) because it's different than the social norm, which says that you should be an employee working for someone else.

I'm saying that there are other dignified ways to live that are different, you don't absolutely have to be an employee at all costs.

Independent work, running a small business, those are other alternatives to live that are equally valid.
