If I needed a generator to run a remote mining operation, and you just told me to just buy energy futures instead, we'd be having a silly discussion. Whether it makes sense for me to rent or buy the generator has more to do with governments, [,tax ]laws, and risks that ultimately manifest as cashflow decisions. You have some valid thread you are pulling on for what are the economics of general purpose compute and to whom, but your argument needs a lot more care to carefully define and make your case and why it is okay to dismiss the outlier cases for instance.
