It is common in Europe for small towns and villages to be quite walkable, have a large relative percentage multi-family housing, and have a decent train or bus connection to a regional hub. Of course, they have the advantage of being around longer than the automobile has existed.
The problem in the US is mostly cultural. Most rural/semi-rural/exurban people think nothing of an hour driving each way. So why would they want what they perceive as a tiny lot, with more expensive housing where they can hear their neighbors when they can get a huge lot and drive a little more?
The non-cultural part of the problem is that the drive-everywhere paradigm is so heavily invested that even in a small walking-oriented European -style village, everyone would need to own a car anyway. If you built a train to a regional hub it wouldn’t solve the problem of the regional hub itself having terrible public transit. Plus, it’s a lot easier to build a road than a train politically.
