Capital constantly needs new frontiers to exploit, and therefore must remove moral and social obstacles that stand in its way. Pseudo-prostitution has already been made widespread via platforms like OnlyFans, it's only a matter of time before in-the-flesh prostitution follows, as you said.

It's curious to me that so many progressives or soi-disant leftists are in favor of dissolving these types of moral and social traditions while being fervently anti-capitalist. It seems that they (meaning the subset who are always looking for new fenceposts to tear down) are in fact the shock troops of Capital.
