Your suggestion is much worse. It'd require millions of dollars.
Doing this might also get yelled at by another activist group for buying up all the lands in the city.
A better alternative: we could just join city council and vote to reject any new building.
Not that I agree or disagree with NIMBY, it's just that your suggestion is much worse than the alternative for NIMBY-ists.
