For your first case while evacuation and such, there are alternatives and you shouldn’t need full internet access for situations like that. (obviously this isn’t the case right now)

People absolutely need internet access in evacuation situations. They need information to know where it’s safe to go, where they can get help, what routes are still open, whether it’s safe to return home, whether their home still exists… in some cases the only communication methods are either internet-based or literally flying a plane in, there aren’t even roads to some communities that need to be evacuated. There is way too much information people need to be able to rely on local communication methods like radio.

And that’s really one of the only other options in these situations. The fibre line (pretty much singular, because the cost to run fibre over thousands of kilometers is enormous) going through the NWT was destroyed in the fires as a fire was approaching Yellowknife. Cell towers can literally melt from the heat of some of these fires. Ground infrastructure is vulnerable to all of the climate disasters our world is currently facing. And that’s ignoring it getting destroyed by actively hostile actors like in Ukraine.

Do Starlink and Musk suck? Absolutely. Fuck them. But satellite internet is increasingly showing itself to be a necessity, and to think otherwise really underestimates the size of our world and the vulnerability of our infrastructure. We need better management of it, but we definitely need it.
