I do care when this use case is harmful.

We shouldn't need to limit hardware for specific usages, but we already see that people won't stop themselves from wasting energy and accelerating world climate if this gives you more wealth and power.

I'd also be up for limiting all military weapons from being so destructive across the globe for example. It's mind blowing how we managed to create so many harmful tools in such a small time span of our history.

But I agree with you when the use case is actually useful for humanity.
