I don't figure it would be that useful for the earth for the power utilization you specify, and that is just when discussing BTC which not every person will have the capacity to get their hands on. On the off chance that we discuss whatever remains of mined cryptographic forms of money then the harm is considerably bigger.

Moreover, what you allude to as futile work is what number of individuals pay their bills and bolster their families.

What might these individuals do at that point? In the event that we are discussing the lower positions then they might not have the assets to teach themselves about crypto, so who might bolster them, the state?
