If your questions are concrete and in the context of Lemmy or the Fediverse more broadly, admins provide the service of paying for and operating the servers in addition to moderation.
If it’s more abstract, i.e. “can people talk to each other over the internet without moderators?” then my experience is that they usually can when the group is small, but things deteriorate is it grows larger. The threshold for where that happens is higher if the group has a purpose or if the people already know each other.

That sounds right.
So the deterioration needs to be managed.
