It's not me that's fixated on ipv4. I would love ipv6. But why aren't ISPs providing it? Why aren't universities and other large organizations switching to it by default?

ISPs don't care. They would rather everyone just use carrier-grade NAT.

Because someone works at those universities or ISPs who is making the same argument you're making. If enough of you all throw your hands in the air and say 'not enough people are doing it' then there will never be enough people doing it. At some point someone needs to point a (metaphorical) gun at your heads and make you all do it or else.

In the meantime, you should feel bad every time you make this argument because you're helping to make the world worse and enabling everyone else to just kick the can down the road.
