The equivalent to banning bitcoin mining would be banning personal vehicles, or banning pickup trucks/SUVs. Banning ICE vehicles would be closer to banning the use of fossil fuels for bitcoin mining.
It's about significant contributors to climate change. If BTC contributes disproportionately, then there will be a call to ban its mining. It's already happening (see China and St Lawrence County, where locals were unhappy that BTC miners drove up their electricity bills)
