| Because we live in a country and state, not just a city. And very often that requires city policy that is the opposite of what current residents want, but is what other people across the country/state want. E.g. if current residents don't want growth, but lots of other people want to live there, there's nothing about democracy that says the current residents' preferences take precedence over people who want to be residents. The entire point of a nation is that it's able to coordinate and redistribute internally, for the good of the country, often against the wishes of a small minority (e.g. the current residents of a city). Can you imagine if every neighborhood and town and city had veto power over everything? Where would you put landfills? Everyone needs them, but nobody wants them nearby to them. So the moral authority comes from country-level democracy, and state-level, being able to rightly supersede local level. |
There are other countries that work the way you suggest, but people prefer to migrate out of them rather than into them.
