The need for supportive communities in SHTF situations is something we talk about often. People know they need a support network because, let's face it, in a long-term survival situation almost none of us can do it alone. However, one of the biggest tragedies to come from the Covid rules has been how hard it is to meet people and establish any kind of community these days. And many of us have learned things about our circle of people that aren't overly positive during this stressful time.
Your own opinions about Covid aside, many states are greatly restricting opportunities for socialization. Some never really opened back up after the previous lockdown.
In my state, Colorado, public gatherings are severely curtailed. I still attend church, but we are no longer allowed to socialize afterward. At the kids' activities, parents are discouraged from sitting near each other and chit-chatting, which was a major social outlet for a lot of parents (myself included) for a long time. You might strike up a conversation with someone friendly, or you might get someone who flips out over not social distancing properly.
This atmosphere of distrust is worse than any virus.
You have your friends, and then there are your "lockdown" friends
We have come together in ways I never would have expected. I don't know what will work for everyone, but I can give an example of how a series of inconveniences gave rise to my own little group of people getting together to process chickens.
