Exactly, that is the idea.

Maybe the relay could return an explicative note (every 24 hours) when the user queries a specific author but the threshold is insufficient, so he is alerted, can zap him and access again the content.
A nice variant of the relay could be use its pubkey as zap target, and allow reading all notes from authors that have write access. This would work well for a team (e.g. a magazine, a project, etc).
The problem is that if you're querying a specific author then the relay can't return a note from someone else, that will be discarded automatically.
I like the idea of relays as zap targets. That fixes a lot of things. Would be nice to have that built in clients somehow.
