> What gives someone the right to tell someone else what they must use the electricity they've bought for?

Well, at its base, the law and force of government give people that right, just like any law we make gives anyone the right to tell someone else they can or can't do something.

Electricity is a common resource. Spinning up new power plants is not cheap and has environmental impact. Overtaxing a grid not prepared for the added load causes all sorts of problems for residents. We write laws all the time to encourage behavior we want and discourage behavior we don't want. There's not reason why electricity use around Bitcoin mining should be exempt from that.
