"With this many nodes I imagine they could almost get realtime video of the whole surface of the planet."
In this day and age - THAT is not a bad thing, as long as it's all publicly viewable.
We're sleepwalking into a bunch of ecological disasters and being able to keep tabs on who's breaching treaties aimed as survival of the species (it could easily get that bad - people can move away from sea level rises and extreme weather, it's hard to move away from a reduction in global oxygen levels) may well be the game changer that's needed to ensure that people actually STICK to them.
