I think OP doesn’t even know what their point is.

They keep saying will continue to perform sex work if there’s no economic gain, but at the point it’s not work. Then the counter argument to that is “there’s many different kinds of sex work”, but the point still stands that having sex voluntarily, being an exhibitionist, or having a hobby of filming sexual encounters are all things that people do for personal gratification and are not considered a career now, or in this hypothetical post-scarcity civilisation.

Like someone else said, it sounds like they are just fantasising about sex slaves. To me it also sounds like OP is overcompensating on the whole “I respect sex workers” virtue signalling.
