Would you also permit hazardous chemical refineries to be built alongside or within residential communities? Are there any freedoms of self-government that you would like to see preserved?
Probably not, but I'd have their site planned at the regional/state/province level rather than allowing each individual municipality to say "NIMBY!" to everything. Because most NIMBY measures aren't about chemical refineries, they're about the working class, about sites of housing and employment for ordinary people.
The whole view that dense housing somehow equals violent crime is decades out of date and largely only ever applied to deliberately-created black ghettoes in the first place.
