I would love it if it were easier for the common person to host their own stuff. Between all the concerns involved (security, hardware, demand, etc.) I'm not sure how feasible it is. I've given it a lot of thought, and have slowly unwound my custom tech setups - from domains, to emails, to hardware. Mostly for the "bus" factor. When my dad died, my mom let his computer sit untouched for years. At some point I transferred the files on it to my computer so they wouldn't disappear forever. But still, a decade later, and it's just sitting there. She never bothers to turn it on.
I have a family, and my wife is not technical in the slightest. If I were to be gone tomorrow, there's no way she would have a clue as to what to do. My #1 barometer for everything I use in life is how easy it is for her to use things.
It's interesting to me how temporary and inaccessible our digital lives actually are.
