I think they're exciting. Archive.org might let you _see_ an old version of a website but it hardly lets you _use_ an old version of that site. Especially if the site in question is a dashboard-like service or single page application. (Imagine google docs, trello, or an amazon service's dashboard.) This is also true with apps. I had no way to go back to the old version of my feed reader app after they updated it and filled it with ads. Flash drives aren't an option if any of the devices in question is lacking of a USB port. My phone has no way to accept a flash drive without some sort of adapter that I don't own. And you're right that _someone_ still has to be there supporting the app. The goal of the distributed approach is that that someone can be any member of the distributed network. It no longer has to be a single central entity that can vanish without recourse.
