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.

Buying Twitter is a top-down approach. Moving to SF en masse and voting sounds like a bottom-up approach. IMO top-down approaches work better for the right and I'm not sure what that would look like for SF
