I used to think just like that (in general, not this particular topic).

Today, it looks to me as a presumptuous way of considering what each person decides to do with they time and lives.

One could as easily argue the oxygen you and I are breathing right now is a big waste of resources.

Let's just let people do what they want to do. If they wanna spin up a machine and run a hash algo all day, just let them.

What's the real difference compared to you playing a game? Or watching YouTube? Or whatever you'd like to?

They're not forcing us into anything, let them in peace...
