You own what you possess. You own those 69 Sats (if you run your own Lightning node) I sent to your wallet with the seed in your head.

You own the Patek Philippe on your wrist more-or-less the same but it can be seized unlike those 69 Sats.

If you want to store wealth Bitcoin is second to none for this reason. You can still have heirlooms and symbols and objects, that is culture manifest and it has its own value.
