One great problem it solves is namespacing all of your styles. I don't have to worry about classname collisions because the bundle handles it all for me. Instead of having one massive global stylesheet, I have a bunch of small, modular stylesheets that fit entirely on my display without scrolling, and I can reason about the output much easier than before.
I don't think communities would put up with foreign ownership of local land where said owner literally never sets foot in a 1000 mile radius of the land they "own." Even following your argument, this type of land ownership (pure speculation) would likely cease to exist.
How loud does a computer fan get when running at 100% fan, with a high pitch almost like a drill, in your experience?
I've just tested with a sound meter app on my phone; granted this isn't the most accurate way of doing it.

Fan on while running and GPU is activated: max 90db.
