i wonder if a resurgence in social clubs like the Elks club/Moose lodge would ever catch on.

i don't know how big they ever were in the past, but it seemed like it was commonly represented in media in the 50s/60s (e.g., the flintstones had a parody of the lodge which would suggest that they were common enough that people were familiar)

I posted a comment that gives a few of my thoughts as to why. How do you propose those problems be solved?

Because voluntary association isn't really allowed in the United States. You are forced to associate with people you don't want to, for a variety of reasons.
