Any fee that is acceptable for "normal use" is not high enough to deter the likes of Google or the big AI developers.

Google, a company that custom develops specialized automobiles to regularly drive ~all the streets in the world for the purposes of having imagery for a mapping app. Google, a company that (before it even got really rich), developed custom book-scanning technology to scan all the books it could acquire.

The big AI providers are in litigation now because even licensing terms that prevent use are no deterrent, they just stole the content they wanted to train their models.

The fee won't deter the cases you want, it will only harm the rest of us.
