My real point is that there is no such thing as a "useless" service. It is a completely subjective distinction. At what point do cars become "too luxurious"?

Either we have a fully managed economy (which I'm pretty sure the historical consensus is clear on) or it has to be guided by attaching costs to externalities.

All this is doing is just picking on Bitcoin because people don't like it. There is no principled economic or environmental argument here, just a biased rationalization applied inconsistently.
