I have looked into proof-of-work in meticulous detail, I have not looked into proof-of-stake. If proof-of-stake exists and eschews the problems I have stated, then what I said here about the problems it creates does not apply anymore.
I have many other doubts against the usefulness and sensibility of blockchains in general, e.g. I have doubts how smart contracts actually succeed to reach their goals in a reality where humans make mistakes and courts are used to settle disputes and ambiguities. But these concerns then only affect the viability of technologies that I and others are not forced to participate in.
Proof-of-work on the other hand, as long as it continues to exist, affects everyone in that in incentivizes burning resources directly for money without regulation, no matter how dirty or wasteful.
