This doesn't work for Patreon, which often isn't merely about "digital assets": while some people on Patreon might be using it to merely sell access to some digital portfolio, many (I'd even say "most") use it as a form of VIP club system, with direct access to the artist, custom work products, physical swag that you receive in the mail, shoutouts during live shows... Patreon isn't a system that inherently scales with anything close to zero marginal cost, at least for most of the tiers of most of the artists I've seen on the platform.
