I agree with literally all the problems in the criticism presented here. I think the problems are real as well. My only issue is that the approach to solve some of the issues generated in crypto industry are either not practical, sustainable, or effective, hence my criticism of the criticism presented in this thread. I don't like the idea of insane power consumption, specially when coming from non renewable sources. But at the same time I also recognize that the incentives built into the protocol (BTC specifically here) are stronger than the environmentalist approach of either killing the industry or moving to POS (which has not been proven to work at scale or in the wild outside a testnet yet). Which is why I think that a better approach is to guide the industry into ONLY using and incentivizing renewables.
