There's a thread on this topic in Aibu, but I think it is also a feminist issue. Giving every person a certain minimum sum (enough to live on) would be an important step towards the abolition of prostitution, among other things.
It would, of course, not affect the special snowflakes who are happy "sex workers", but it would mean that no woman has to work under inacceptable conditions - including, but not limited to prostitution.
