A basic friends-only system isn't that expensive to run. A low-budget operation like Craigslist could do it with a modest staff. A low fee or infrequent ads could bring in enough revenue to keep it running.

The expense depends on what the baseline for "basic" is.
I believe today's average consumer would want basic features to include photos and video sharing. (This consumer expectation having been conditioned by previous $0/month social networks like Facebook.) Needless to say, this requires expensive datacenters with petabytes of harddrives. Rising storage infrastructure costs and was the #1 driver of Facebook costs in 2006. It may still be today. I don't know. I believe storage is still Snapchat's biggest cost component of Google Cloud payments.
So either run a text version of a social network or put storage limits to keep the social network "cheap" to run. My guess is that the typical non-HN type of user would prefer the ads so it's still $0 per month with the ability to share lots of baby photos.
Now a "Freemium" app might work. Text is free. Pictures up to a limit are free. A few seconds of video with an expiration time is free. More pictures, longer video, and long term storage all cost.
Fortnite is "freemium", and bringing in over $1BN a year without ads.
You could also treat brand pages as what they really are: advertising. Charge them a weekly/yearly fee to have the ability to run such a page.
The technical aspects of such a service are trivial. People try to build new social media sites every day. The problem is building up a network effect. Getting to the scale of Facebook may not ever be possible again for a small startup because the friction for switching services is so great. Until there is some massive technological leap like the internet again, there's really nothing compelling enough for the average person to bother.
I'd really love to see a resurgence of blogs, but any replacement for Facebook needs adequate answers to the kind of questions that blogs always left unanswered.
I think you'd have a hard time finding people that would believe that infrequent ads would remain infrequent.
Well, that, and the other thing FB got really really good at: I hardly use FB for friends. I use it to track all sports/music/scenes I'm interested in. It has become my number one source for tracking events. There's, as far as I know, nothing which comes closes in aggregating all of that.
