> lot of creators get their revenue through donation, either one time or recurring

I keep hearing this, but I have yet to see one person truly live off of donations. Patreon is backed by expecting services in return, so most Patreons are definitely not donations.

It is probably possible, but only for people making funds that are already at points many would call "wealthy".

>we could pivot to UBI instead of dedicating ressource to enforce fake scarcity.

I'm all for UBI. But I don't even see that in much talks in the US, just a few tests by private companies (how very American). Might as well have short term ways to survive while just blueskying entire economic models.
