The fashion industry alone has more climate impact than air traffic and maritime traffic together. Aviation contributes around 1% of air pollution (though 5% of greenhouse effect, due to high altitudes).

But all of those (transport, fashion) provide utility. BTC usurps nearly 1% of world electricity without providing commensurate discernible utility.

I'm sure people who don't fly or follow fashion feel the same way about the perceived utility.

I for one think not having to pay 20% for a remmitance for someone who is trying to help their famiy in another country has huge utility, maybe others disagree.
