> A hammer can be used in construction or to bash someone’s brains out. Nobody ever mentions banning hammers because someone used one in a f’ed up way.

Guns are perhaps a better analogy than hammers here. Not a perfect analogy, but a better one. > for the environmental damage part: in a free market you cannot really control what people are doing with energy. You use the energy, you pay the bill. End of story. If the profit you’re making from the activity is greater that the money you are putting in people will do that activity. That's not a rebuttal, it's a description of the problem.
