Your first mistake is assuming that the power used to secure the Bitcoin network is a waste. It is clearly not, since thousands of people believe it is worth paying for.
The second error is implicitly assuming that the number of people Bitcoin serves is correlated with it’s power usage. You could serve the same number of people as the banking sector does now without increased power consumption when you bring layer 2 or 3 solutions into the picture.
