The problem with owl:UniqueProperty exists regardless of the proposed closure rule. If you have both Jenny ex:age "10" . and Jenny ex:age _:x . _:x xsd:integer "10" . in the same graph, you will still get the conflict with ex:age a owl:UniqueProperty . since "10" will denote the literal and _:x will denote the datatype value. This is a fundamental incompatability with the coexistence of the inline and bnode based idioms and owl:UniqueProperty, and may even be construed as evidence of a problem with literals always denoting themselves...
