You can't drive up the cost of "waste", all you can do is use it such that the waste is decreased. If people want to make hydrogen with it they should do so. As I said, the Bitcoin network is not capable of bidding for energy at higher prices.
Your argument boils down to: why aren't people doing this uneconomically viable thing that I think is better than this other economically viable thing.
Think of all the useful productive things that you could do with all that precious time and energy you personally waste by shilling and hyping Bitcoin. You could take a nice walk. You could pat your dog. You could take a bath. You could write a poem that makes somebody smile. You could write a computer program that solves somebody's problem. Find something productive and constructive to do with you life and the limited time and energy you have here on Earth, instead of wasting your energy shilling and mining Bitcoin.
Oh, give me a break. Get over your delusions of grandeur that you're "without a doubt" such an essential savior of the future of humanity. The last thing humanity needs is yet another Bitcoin shill, making baseless arguments full of broken assumptions and excuses that ignore the science and the facts, and encourage pollution and global warming and fraudulent get-rich-quick pyramid scams.
