Ownership in the sense of a lease, I suppose; for all intents and purposes,
a leased item is yours as long as you comply with the terms of the lease.
The same would apply to registered domains; except that, as the registrant,
I *do* fully own the user names under the domain, for a long as my lease of
the domain is valid.
Of course we are *ALL* property of our respective governments, and have no
intrinsic rights over our own lives; other than what our governments are
willing to allow; i.e., we don't even own our own selves.
