Like, I get what you mean, I do.

But it's simply not accurate. Great as a shower thought! Just not accurate regarding the motives of all prostitutes and porn actors.

It isn't about poverty, though that is there. It isn't about addiction, though that's definitely a big factor in both. But it has never been that simple.

I think what would be more accurate is that in a post scarcity environment, prostitution and pornography would cease to be about necessity. You would see way less of either, with pornography possibly becoming only self produced.

Prostitution would probably cease to be an exchange of goods or currency, which does mean it would be eliminated on a semantic level. After all, if it isn't an exchange of goods/currency for a service, is it still prostitution, or is it just two consenting adults having sex? At that point, it's no different than hooking up with someone you met via something like grindr.

But that doesn't mean the basic idea of someone having sex with strangers for some kind of exchange would die entirely. It could end up as a more direct exchange of services. "Hey man, if I give you head, could you help me move this fridge?" "Sure dude, sounds like a fair trade to me." You might even still have street level hooking, where people are just looking for some kind of exchange of sex, even if only for the rush, but it isn't about money. Wouldn't be much, most people aren't into that. But there are people into that.

The internet put a huge dent in the porn industry. It didn't kill it, and I don't think it can. But people making their own porn for fun and sharing it changed the industry. Enough that I'm certain it will never go away entirely, though the exact shape of it may be so different as to not really count. But porn, at its core, is not about the porn industry. The industry could well die within years of scarcity disappearing, maybe even less time. But you'll still have people making movies of themselves that they allow other people to enjoy. You'll likely even have hobbyists that have skill with the film making that get asked to do the filming (I know a guy that does exactly that).

But, yeah, good shower thought!
