It's going to depend greatly on your geo location and socioeconomic circumstances, but a homeschooled kid who interacts a lot in the neighbourhood (big "if", IME; those kids all have a lot of school friends) is still going to miss out on broader social, cultural, racial and financial exposure. Example: my white, middle-class kids have a lot of people exactly like them in community groups and sports clubs, but lots of eastern european & asian immigrants in their school classes. This is super-important in elementary school when they're far less aware and insular about interacting with people who are "different" IMO

The venn diagram of 'homeschooled' and 'goes to church regularly' is not quite a circle but its not far off. Moderate to large churches also provide a great deal of socialization in this same way. Cross-socio-economic, racial, and other bases, all with a shared value system that creates a localized high trust environment that affords a greater degree of freedom for child autonomy.
