Sure, but that was a problem that already existed. People already sell other people's artworks / pictures / etc.. Having to copy a file rather than a link is not a significant barrier.

Presumably you're getting the link from somewhere reputable - the creator's own site, or their patreon/twitter/etc.. Sure, a scammer can create a fake profile to impersonate them - but again, that's something that already happens.
If it's a link, it's available to anyone if they have it
It's not helped that there's no preview of the content or creator's site branding to give some indication of an intentional connection between the creator and paid link.
How does anything like that help though? The scammer can download the file and host it themselves and you're right back where you started, and that's always going to be the case.

This is a system just rife with abuse potential.
