"Shocking" is the word you're looking for. Keeping the lights on would be easier if we wouldn't have an internet resting on a few shoulders.
Holy shit no. This is the sort of thing that gets kooky politicians randomly turning off the flouride in a city's water supply: https://alaskapublic.org/news/2021-12-15/anchorage-mayor-tur...
Things aren't as simple as you seem to think they are.
Well that's a non-sequitur.
Yeah, why even have ASNs, BGP and distributed network infrastructure when we could just have GooFlareZon host it all, with basically no drawbacks?
There is many good reasons why the internet is distributed and why that was the architecture that allowed it to go global. Going back from that would do no one any good except the ones who ends up the new owners.
