I think this idea of villages of 30 people where you don't talk to anyone is just a fantasy. Even the Mayflower had 130 people to just set up their new town.
I didn't say that—I said you'd regularly interact with only ~30 people (give or take). You'd probably be on good terms with a few dozen more, and it's been demonstrated that we really lose the ability to have relationships entirely by about 100-300.
The average city today has about 8x that number of people per square mile. That's entirely unlike anything that evolution equipped us for, which is why I object to OP's assertion that we all descend from extremely social people. By modern standards we absolutely do not.
in what way do you feel like your expected to talk to anyone in our modern world? even here online, there's no expectation for you to respond to anything I said here
There's a huge difference between going to church on occasion (or even weekly, which was not always the norm) and living on a single acre of land with 30 other people.
