Should a community be able to vote to exclude people who don't make a certain amount of money? How about people of a certain race or sexual orientation? These are freedoms that supersede the desires of the community, and since the single-family zoning laws are roughly paramount to gatekeeping by income, it makes sense to eliminate them.
I will note again that eliminating the restrictive zoning also doesn't equal a mandate over what landowners must to do with their land. You're welcome to keep your plot as-is. You just can't tell your neighbor what to do with their land.
No one is excluding based on class. They're simply full. You have no right to be somewhere where someone else already is. Prices are only high because a bezillion people want to try to get in the same place. Just go live somewhere else and there's no more problem. This argument that since there's not enough housing for all the outsiders that want to move in, they must build housing for you (or change their desired zoning) is completely entitled.
The municipality IS keeping it's plot the way they want it.
0.25 acre plot is not a country, it's a part of something else, and at that something else level, it is valid to make the same sorts of decisions for themselves as the homeowner does for their lot.
I would hate life in an HOA. What I do about that is I don't move into an HOA, not to move into one and demand that they let me raise chickens on "my own property".
I think I was 15 years old or less the last time I thought zones were some sort of travesty of injustice. Same a taxes.
