And a registration system that amounts to a more complicated captcha doesn't? How long until someone starts farming accounts and run bots that jump through these hoops as well?

It's only "fundamentally broken" if you need to build a perfect system that needs to accept 100% of legit PRs without raising any level of friction.

But we don't need that. Pfand systems are not meant to be perfect, and they are not meant to the single solution to any problem involving the commons. They will not get rid of all bad behavior, but they will certainly bring it a global-scale problem down to levels that can be then managed by other smaller, context-aware systems.
