I agree that groups are the best way behind family groups. But if you don't have an prepping family or even an family in the near then this group is gone. So an "normal" group will be left.
My peoples an i had an group and still have, but a lot changed during the corona time. OK, may not changed, but it showed the problems with groups in good times:
The most of our group members turned their priotities into their families - which i absolutly agree and i think it's an reasonable and good thing. Family always should be first. But about this the group was work only halfway after. We still support each other, especially by organising stuff or informations we need (during the lockdowns not everything was aviable). And we will go ahead like this in future too.
For myself it showed i should bring my preparations in an level where i can always help myself, because not much left from my family and my 81 years old dad is living just to far away.
I'm absolutly not frustrated about the upshowing problems and i was, written by my history end experiences in life, prepared for an situation like this. I just have seen for myself i could do a bit more, increase my skills, extend my planning to an point without others.
OK, some may will say now "go and look for another group". It is an argument, an idea of course. But there's an problem i do have with myself: It's hard for me to trust new people enough in an extreme situation which an SHTF is. Life experience even...
So far i can absolutly understand people like
@bigpaul who say the won't have to do anything with others. Maybe i'm just an bit different in thinking because i still will give other people an chance.
