Yes it ends up as heat, but with some forethought, it could be used to eg heat people's homes rather than as waste.

You can say that about any waste heat.

In really, it’s not convenient to move all waste heat to where it’s more needed.

Modern industrial scale insulated hot water district heating systems can do dozens of kilometers with the water cooling down only by a degree Celsius.

It's always more convenient to ignore externalities. That doesn't mean we should be okay with only bottom-of-the-barrel solutions.

These days it's not rare to have data center heated buildings. I guess crypto bros are just not thinking about this. But technically if could be done there too.

There was a startup in EU which explicitly sold heat from crypto mining to the local energy provider. IIRC it was also here on hacker news some time ago.
