CMV: Bitcoin mining using non renewables should be banned immediately.

Global warming is a serious threat to the survival of the human species and it's insane we are adding to this problem for no good reason. Currently Bitcoin mining consumes more power per year than the whole country of Argentina. There would be hardly any downsides in banning the mining of crypto currencies using non renewables and the benefits would be immediate.

Even with a 'carbon tax' mining for bitcoins should be banned immediately if it's being done using non renewables. There is no effective way to capture carbon at this point and it's unclear if there will ever be. 

What am I missing?

They are buying this energy legally. They are paying for it. Producer of this energy will still produce that energy and sell it to others. So what is the point of that ban? 

That "dirty energy" will still be there, the only change will be distribution - BTC mining will start getting fueled by renewables and renewable energy that were used for other purposes will be used to mine BTC. At the same time, "dirty energy" that were used to mine BTS will be used to supply those who aren't supplied with renewables anymore, because that energy is being sold to BTC miners. 

Your proposal solves nothing. It will make BTC mining "cleaner" by making other energy uses "dirtier".
