@cathal Not in the way you mean. You can backup everything since the public feed contains all the data you want to backup. But there's no way to _prove_ that your new home is the same you.

I believe solving this technically (automated, so that everyone can do this at will anytime) is bad. Users should in the ideal case be with services they trust and CAN influence. Instead I think the priority should be to make installing + running your own little group instance easier. To incentivise groups of humans to set up and organise themselves and real democratic hubs (maybe online, maybe in meatspace).

The nomadic identity thing just strengthens the view that you "are" somebody specific. That the individual is more important than a working democratic cooperation between people/users.
