Few things - I think the whole AR world could end up pretty sad. Imagine I go to a friend's house and all the art on his walls is mine? Like a world I've chosen where I'm not exposed to anyone else's tastes and choices? That aside - isn't this all still likely to rely on something central? I mean it sounds like you're talking about something pretty close to Ready Player One (which was owned by a central corporation)? Any AR world (in order to be successful) is going to need a whack of capital (Google, FB, Apple) and then vested interest in making it successful/profiting from it - at which point why do you need a Blockchain to own items? If you were the corporation running it, wouldn't you just implement your own "in space" ownership? Not saying it's better or worse - just isn't that more likely?
