That's interesting - does printing (not earning!) a dollar cost as much in energy? Valid idea.
The 'human rights violation' part seems thrown in there. I imagine some Treasury sweatshop with rooms full of slave engravers covered in ink, working 20 hours a day.
Where do you stop with that? Everybody needs money; there are more people around all the time; you have to print more money. And is it 'stealing' to put more value-tokens into circulation - they have no intrinsic value?
