> ...all of these server applications would have to be easy-as-an-iphone to set up and administer. Right now, such apps don't exist, because there's no market for them. But if the market were there, millions of people with hosted servers just sitting around, you can imagine how quickly they'd get made.
I don't know about this. People have phones and computers, too, but we still have gmail instead of personal mail servers, and we still have reddit instead of usenet. As a developer I definitely prefer serving web pages to shipping iphone apps (never mind physical CDs) because the deployment and maintenance stories are so much simpler. In other words, even if millions of personal servers existed already, why would a developer prefer to write Self-Hosted!Instagram instead of just Instagram?

Because urbit is designed to make that an easy thing to do. Say you've got a webserver, and you want to put a picture of your kid on it, but you only want the server to serve that picture to your Mom. On unix, that's really complicated, you need to do a lot of things to make that happen - not just implement a web app that includes authentication and give your Mom a new login and password to memorize, but also configure the web server properly and make sure your server is locked down and stuff like that.
On Urbit, that would be really easy, the equivalent of "mkdir mom; chmod +r mom; mv pic.png mom", because it abstracts away things like cryptographically verifying identities in the same way that unix abstracts away sending a file to a printer.
