Sorry, but this seems like a privileged solution.
Let's say you're a one-of-a-kind kid that already is making useful contributions, but $1 is a lot of money for you, then suddenly your work becomes useless?
It feels weird to pay for providing work anyway. Even if its LLM gunk, you're paying to work (let alone pay for your LLM).
Not that word, in the context of contributing to an open source project that you're likely already benefiting from.
ie, if you want to contribute code, you must also contribute financially.

It is a privileged solution. And a stupid one, too. Because $1 is worth a lot more for someone in India, than someone in USA. If you want to implement this more fairly, you'd be looking at something like GDP or BBP plus geolock. Streaming services perfected this mechanism already.
