Also my theory:

In a very far future when AI & robots have taken over, call girls will be among the by far highest earners across all jobs. That is not going to be tomorrow or in 10 years, therefore "in a very far future", but its clear that this will happen (unless other effects like prohibition of that business may kick in)

Why? Wouldn't it be the opposite? If people are just gonna roleplay having an actual relationship, robots can do that cheaper and better in the future.

It sort of happens with prohibition too. And illicit activities have higher price tags than licit ones.

I think the was already understood. Anyone remember the 'companion' in the show Firefly?
