>That number should have been at least as big as the population of the planet.

Addresses can actually be up to 128-bit. I think the idea is that addresses longer than 32-bit are just assumed to be bots, but that convention would probably be changed if Urbit gets popular enough for the 32-bit limit to matter.

...if Urbit gets popular enough for the 32-bit limit to matter.

I'm trying to think of a 32-bit address space that was found to be too small... I know there was one, it's on the tip of my tongue...

That was an address space for computers, not people.

The stated reason is that Urbit addresses are for "responsible adults", and that each responsible adult will have 1 address. Each address has 96 bits worth of subordinate addresses, so you should be able to give all of your devices, dependants, etc an address.
