If people were open to the idea of community units there would be no need to propose them, they would already exist
I don't believe this is true at all. I think this is a consequence of the systems we have in place.
There are two big obstacles to rebuilding communities. The first is that no one trusts each other. Community units were an institution that promoted trust in society and dissolving them naturally led to lower trust. But additionally, the systems we depend on to stay safe are rapidly breaking down and we're left to fend for ourselves. If we start a community and one person turns out to be a thief or a psychopath then there's fears that there's not a whole lot we can do about that. Not to mention that we're rapidly approaching a point where parents are so paranoid that they don't let their children around other adults in general. There's a trend towards anti-social behavior in our society.
The second is that the way our real estate is set up, you can't have a group of friends buy or build a bunch of housing in close proximity to start up a brand new community. So given how nobody trusts each other already and you can't just start a community with your friends, it's difficult getting going.
I'm not the right person to ask on how to fix these issues but it is worth thinking about.
