If you live somewhere that's reasonably dense, this is possible. I live in a very walkable city that is also socially quite dense. Most of my social links are people who live a walk or a short bike ride away. During the warm months, if you are around town you will see people you know, and have the option of conversation. Put simply, you feel like you live in a community without having built a commune or something. Unfortunately it's kind of hard to tell what cities have this "social spatial density." There are denser urban areas that feel less communal, and far sparser ones that seem moreso, it's related to overall population density but not perfectly so.
