Thank you for writing this! I've been playing around with writing something similar and I getting lost going way too far up the concept chain. Like, ultimately, I self host because... Capitalism?

In my ideal world, one tech savvy person would run services for a group of their friends and family. This makes the concept more mainstream and accessible, while also creating social cohesion for that group. I think we've monetized too many of our relationships, and often have no real reason to be in community. This is a big change from most of human history, where you depended on community for survival. Building lower-stakes bonds now (I run your email, you help me fix my car) helps avoid the problem later when you really need help (old, sick) but have never practiced getting anything you need except by paying for it
