Maybe this is a the case, however there are, I would guess at least a billion people on earth who play games. there is nothing even close to that using blockchains. If blockchain energy usage is even vaguely in the range of games it can still be considered an enormous --possibly-- unnecessary usage of power

Maybe this is the case, but when we start judging what constitutes unnecessary usage of power, we get in the business of telling people what they can and cannot do with hardware they own. Last I checked, the HN crowd really doesn't like that kind of thing.
