You make a good point. I'm not much of a gamer, so I'm pretty ignorant of that world.
I like your distinction between a consumer -> producer model and a social platform model.
Content on the internet might be more like a social platform than the traditional model of producers and consumers. Maybe we've been thinking about it like there are the people who make the content and the people who consume it and they are completely separate, whereas on something like SN or nostr they are less distinct.
Incidentally, this is where I think ecash comes in. Something like boardwalk cash with a stable dollar balance and the ease of exit/entry via lightning would go a long way to letting every platform function like SN. I can imagine a platform that let's you buy ecash tokens with a credit card or with sats and smooths the on boarding process.
