How exactly the system is trying to maximize waste?

In fact, miners did more progress on efficiency in terms of pure hashrate/watt with a million time improvement in past 10 years, than banking industry ever.

It is demand, that is driving the energy usage, not the system on its own. I agree with the person above, that it is basically justified by increasing consumption of the service.
