Elon didn’t start a new social network, he took over Twitter. You don’t need to start a new city, you can take over existing ones by just moving there en masse and voting for your candidates. You don’t even need 44b. This is hard to do, but it’s easier than moving all the intellectual capital out of SF. Network effects are hard to disrupt.

have to echo terrible analogy, elon is among the few in the world who could have purchased twitter

better one is gentrification of neighbourhoods (which includes voting intentions), this is doable municipally maybe? 

the more impactful effect was elon gentrifying twitter via policy for righties / transphobes / etc
