It's a weird hypothetical, but I think it would: if you need something, just teleport and grab it. With the exception of personalized items (basically just my computer these days), I don't care much if somebody takes something I own given that I could get something equivalent easily. As long as the technology was symmetric (that is, everybody had equal access to it), I think it would just make allocation of most items more efficient. Why should I own a hammer that I use once a year if I can just grab it from somebody who isn't using it at the moment? And then they could grab one from somebody else when the time came. The issue with personalization actually has a parallel in the IP--there is copyright and then there is privacy; the two are different and it is eminently reasonable to support one but not the other. Now, there would be some issues with your hypothetical world (e.g. who would produce stuff in the first place?) but I do not think they would be insurmountable. So yes, I think that would make owning small impersonal items obsolete.
