If they don't like it, they can move.

Or do you mean that existing owner should be required to get their neighbors' consent to do what they want with their own property?
Anyone selling their home would, all other things being equal, prefer to sell their home to an neighbor with which they have a relationship then to a random person. The neighbors should make an offer if they really care.
Is Ferrari "not allow specific groups of people" (I am in that group) to buy their cars by not pricing them the same as a Honda?
To use your example, it's as if we were to restrict car production to mostly only Ferraris. And then if someone can't afford a Ferrari, we tell them to buy a Honda - but there aren't many of them to buy.
My town is being more strategic about it. They allowed businesses to come in first and expanded out the robustness of the local coop's electric grid and only then did they allow appartments and they are doing them in stages to make sure the area can handle it. This is important in an area where not everyone is even hooked up to the city's water supply or has access to city sewage.
In areas where the power grid is struggling to keep up with demand, the municipality will need to plan with that in account. If you expand housing in an area where you've made driving the only transportation option, that will straightforwardly lead to more cars on the road. And so on.
But at least in my area, municipalities largely seem to be trying to keep housing density at or below the level it's at now, which is a problem when we're facing a housing shortage.
