That pollution is what protects the integrity. It's not waste. It's like a standing army patrolling a bank. In fact those miners are the number one private security of any currency or bank in the world, by orders of magnitude. And second, every dollar blockchain companies make is a dividend of that army patrolling the bank. Not a whole lot of counterfeit bitcoins going around, unlike some currencies I could mention. Treasuries also spend a lot of money protecting their currency, the Secret Service for instance, which works for the Treasury of USG, is mandated to stop counterfeiting. Who gets better results for the money, bitcoin or the Treasury?
