If you’re thinking about giving me any kind of grief over this, talk to the proverbial hand until you’ve read the long version.
Short version:
Yes, “how will artists get paid” is a question that we (the ones who wanna abolish copyright) haven’t fully answered. We’ve got a lot of partial answers and half-solutions, and arguably there are a lot of starving artists even in a world with copyright, yours truly included, but we don’t have the full on whole solution here.
The drawbacks of copyright are so big in how they create artificial scarcity where there could’ve been abundance that I still opposed it.
