It is not fault of bitcoin you are burning oil/etc for mining it. Use renewable energy.

...which could have been used to replace productive fossil fuel expenditures. It doesn't matter how you fuel egregious waste; its still a pointless thing to do?

I'd love for that to happen! But as it stands, when you use electricity, you're using whatever the grid supplies. And for Bitcoin miners especially, this power largely comes from burning coal.

Look up energy consumption of other worldwide services, like gold mining. Then get back to me.

Look up whataboutism [1], then get back to me ;-)
