A more approachable solution (for the general public, at least) would be a payment processing service that takes the risk of working with adult content creators. But that seems like a tall ask, especially for a problem that's pretty niche. Porn makes a lot of money, but not for the people who're just handling the payments. Or, rather, it might make them a good amount but it's probably the same as the profit from other industries, except with added risk.
