> I think it's way better to make a community grid.

Indeed, like Internet, autonomous networks with connections.

US subdivisions can be a micro grid, a few hundred homes.

There are a lot of condo communities, the common elements (roof, etc) are the HOA responsibility. These can do community solar and grid.

In the metros of third world countries, there is a huge growth of gated communities with high rises. These can be net zero with their own production and grid.
