Proof of Work provides scarcity that makes crypto work. Stake just removes the physical scarcity so it fundamentally can't work.

I think proof of storage or something would be more interesting as a (partial) solution to the crypto folk wasting electricity.

Ideally as proof of RAM though. We don't want them abusing cloud storage plans.

Why is scarcity required to be physical? And if it fundamentally can't work, why does it seem to be working by the metrics?

The reality is, if crypto requires a proof of work system that burns energy for nothing, it’s not a system we as a society should be using.
