Well it's obvious you can't heat your house and earn money at the same time continuously. Bitcoin is no magic perpetuum mobile zero-point energy bending-physics solution but it's true that you can minimize the waste.

That sounds just like any other investment, or am I missing something?

Bitcoin basically is money (a store of value and medium of exchange, with some speculation on increasing future value thrown in that won't change the logic here).

Increasing the amount of money in the world does not increase the amount of goods and services in the world. Thus turning energy into bitcoins will increase any other goods and services but instead results in more money chasing the same amount of goods and services.

Just as one gets apparent economic benefits from paying people to dig holes and fill them, one can get some appearance of benefit from resources being diverted to bitcoin mining. This is OK as long as we imagine an unlimited external resource world we exploit however we want but once you get to a world we have finite atmosphere, finite biosphere etc and pumping enough C02 into these can kill all of us, this sort of approach is becoming untenable.
