No concept of ownership is a stretch. If you have the keys to a Bitcoin wallet, you own that Bitcoin wallet. If you lost physical cash or gold, it would be like losing your keys to a Bitcoin wallet. No one would replace your physical cash, gold, or Bitcoin, if you lost it. However, that doesn't mean that you don't own that physical cash, gold, or Bitcoin, at least while you have it in your possession.
