I don't understand the difference. We're not talking about trademarks, parents, or copyrights here. I don't think we're talking about read or write access either. What does it mean to own data? Wouldn't that require that there be a ledger somewhere that kept track of which data had been transferred to whom? Property rights are typically accounted for and enforced by an authority and when I look around I just don't see anything like that for data.
