I know I'll get hated for this on Hacker News, but this has been solved quite well on the bitcoin & Nostr side of things. It's easy to tip couple cents or whatever amounts and there are many apps / websites that support that.

The main difference is that using the legacy dollar rails is super annoying for small amounts, since there are multiple banks/companies on the path between you and the author you are trying to tip. And each of these intermediators needs their $$$ from you.
