I grew up in a setting with substantial resemblance to this. Colony in South America where the majority of the people were my cousins. Elements of Amish mixed in with a community setting. Hierarchy was largely determined by participation in the church. The intersection of religion and community governance were major factors in constantly changing tensions in the community. I know Amish here in the US who have some of these values. Sexual abuse is prevalent in these communities and is easily hidden so that's probably what I would fear the most in a community like this. I think shared values and a constitution for the community is more important than it being family. There needs to be a predetermined and well documented exit plan as people will at some point want to leave. Note that religion draws people together but often pushes them apart.

Overall my perspective is this would be fantastic if done well. Individual property rights still need to be protected. AI would be extremely helpful in thinking of scenarios that should be documented in the constitution.
