@richlitt oh, and I forgot to say! On your point about how the internet is not inhabited space and thus "homesteading" is not relevant!
I would say it is. The internet (to the extent it is useful) fills our attention, our relationships, the data exhaust of our lives, our public discourse, etc. So while it seems to be "a land without people" it actually always is a means of colonizing existing people and commons through commodification and surveillance.
