> On one hand I want to stay YIMBY here
As far as I'm aware, the YIMBY "movement", or whatever you want to call it, is pretty squarely about housing development. It's not about saying yes to building anything and everything, but saying yes to new housing in particular.
For example, https://newyorkyimby.com/ is pretty much exclusively about housing.
It definitely also applies to infrastructure like building out clean energy or highways. My connection there was to say, yes build a data center so that we also need to build more energy production. I feel like a lot of people view the current problem from the lens that energy is a finite resource, when its also something that can be expanded.
