Maybe I am still misunderstanding, but I think that you rare still saying that a urn/doi approach is compatible with Linked Data, or at least is not harmful. I think differently. urn/doi is harmful - once it comes into existence, it is very hard to avoid the problems of people using them, and then you have to start working out where the server might be. I am quite happy with people passing round http://foo.com/bar/urn:baz.quex, as this is resolvable; I just don't want things that don't use http. I think Bernhard's questions suggest that your comments might have been misinterpreted by him as I did, that urn: is acceptable as a Linked Data URI.
