This greatly confuses the concept of ownership. If I physically control gold, then I have some guarantees about that ownership. Someone can physically take it from me, but I can, at least, make that difficult. If I own gold credits, then I must trust the holder of the physical gold, both to honor my credits and secure the gold. If I own Bitcoin, it means I posses the private key that enables their spending. I have to trust the collective actions and incentives of the Bitcoin network, not a single party. I think it's very clear that these are wildly different notions of ownership, and that they may be valued differently. Equating the transfer of gold credits to Bitcoins fails to account for these differences.
