residents would be able to come and go as they see fit
When I said self-sufficient, I didn’t mean that nobody ever has to leave, but that ~95% of daily life can be lived without leaving the zone. And that is an aspiration, not something that breaks the proposal if it can’t be attained.
If you have a community of vaccinated people, the nice thing is that even if some of them have jobs that put them around non-vaccinated people, first: that person is less likely to get infected at any given point in time, and second: if/when they do get infected, the people they are in contact with will be much less likely to get infected as a result. Both of these combine to mean that someone who lives in a vaccine-only zone will be better-protected than someone who lives outside of one.
I agree that there transaction costs involved, since moving is not a small deal. This can certainly slow down the proposal relative to the ideal, but it hardly seems like a killer argument against implementing vaccine-only zones (as long as it is ensured that implementing the zone doesn’t require forcing any existing population to move, i.e. founding in a currently sparsely populated area)
