Monetizing energy

self.Bitcoin1m ago
I know a common theory bitcoiners use is that mining monetizes energy but energy is obviously already monetized obviously. I am a Bitcoin proponent but I just don’t understand this argument. Wouldn’t it be better if Bitcoin were more energy efficient or use another layer that is more efficient. I love Bitcoin for decentralization and the freedom it provides and energy usage is just justified because of those aspects. I just don’t understand why the energy usage is seen the way it is by some. Maybe I’m missing something.
