I don't understand the climate change comment - not yours specifically, it is common. If POW blockchains are genuinely useful (perhaps indispensable) in this way, why does it matter if it "costs" some emissions to keep in running while also providing orders of magnitude more value that would go into... reducing emissions.

> providing orders of magnitude more value

That’s the reason you keep hearing the argument: proof-of-work blockchain technology has not yet demonstrated that it provides “orders of magnitude more value.”

Because the cost is well in excess of the value, and the value won't go into reducing emissions. In effect, it's just people destroying the environment in order to line their own pockets. That's the game we need to change everywhere.
