> So when you talk about "the costs being borne by the same people who derive benefit", to my ears that sounds very tone deaf

I fail to see how suggesting that costs should track with benefits is tone deaf, or even particularly controversial. All human activity (or any other activity for that matter) meant to produce a benefit will come with some attendant costs. Doing our best to set things up so that costs track with benefits should minimize the costs imposed on people who aren't benefitting. How is that even contentious? This applies across time as well as space. So the assumption that I don't care about costs borne by future humans is erroneous. Will we ever figure out a way to make the costs fall perfectly? Of course not. You're right that costs are not always readily apparent or even easily predictable, and that's assuming we all even want to do the right thing. We'll get it wrong. But we'll get it less wrong if we think hard about how to solve the coordination problems when we do see it happening. I don't see any other alternative, except just to stop all human activity so there are no costs at all.

> Implicitly accept? No, I think we should explicitly reject frivolous energy use

You're just using the term explicit and then assuming (implicitly) that we all basically either agree on what constitutes frivolous energy use or that any disagreement we have is irrelevant. If everybody agreed on what constituted frivolous energy use, the suggestion that we reject it would be trivial. But some people think using energy to secure PoW blockchains is useful. I do. Other people think using energy to run servers hosting TikToks is useful. I don't. I also don't advocate taking them down because I've assumed everybody agrees with me. Like the author of the article seems to do, you gloss over the entire sticking point, which is that people would like to use resources, including energy resources, for different things, some of which we will disagree on. We should minimize the amount that they can impose their costs on us and accept that if we want the ability to use energy to do things we perceive to be valuable, we have to extend the same courtesy to others.
