@deadsuperhero I have bought things from people on the fediverse and commissioned things from several other people on the fediverse to keep making more stuff. I see people on the fediverse selling stuff every day.
I'm not sure you've really made the case for why you think these things need to happen on-platform, putting stuff like "dealing with taxes," "dealing with fraud" and "dealing with copyright violation" etc on the plates of platform administrators who already have too much to do.
It doesn't really seem like you've thought through what adding revenue and commerce to these platforms really entails.
To me it sounds like you're really making two arguments simultaneously: the first is that we need to financially incentivise people to join the fediverse and perform here, and the second is that people need to be able to support each other by buying and selling and commissioning.
Only the first of those arguments requires monetization of the platform, so it kinda seems like you're lumping those other things in to kind of support your main argument. (That we need to "monetize" so that we can attract TikTok and YouTube stars, who expect to be paid.)
Is it really that important to entice people who don't want to publish here to do so?
