The ‘freedom’ they want only extends to having the freedom to do what they want regardless of how it impacts anybody else.
The vast majority of these people don’t want isolation. They need other people to exploit. Edit - or they want the freedom to exploit other natural resources (no doubt they see humans as a natural resource to be exploited) regardless of the impacts on other people, now or in the future.
I think they must have thought: ‘Well we thought four and a quarter billion was going to be enough. We don’t want to repeat the mistake, so let’s create an unimaginably large address space.’
Which, with the benefit of hindsight, now looks daft itself.
