I hear you, Pedro, but picking up your final point, if Bitcoin is currently using anywhere near 1% of the global energy budget while its value is (wild guess) less than 0.0001% of the value of the global economy, what on earth will it be using by the time it’s at scale? And, by extension, I’m sure the banking system uses a staggering amount of electricity but that industry (whatever you think of it) has a turnover measured in trillions of dollars, supports millions of jobs and is essentially the backbone of world business, finance and household prosperity. Can your substitute for central authority do that? And if it can, will it need ALL the electricity? :-)
