> If you can't hold anything in your hot little hand or touch it, it doesn't belong to you.
society has built law and order upon natural chaos. What belongs to you is different from what you can hold in your hand. For example, a land title, which is only meaningful if everyone else respects the title. The gold in the bank's safe is still yours, even if they deny access in the middle of the night, when it's inconvenient for them to give you access.
Crypto's worth(lessness) is not due to it not being in your hands, nor that you cannot touch it.
If you can't hold anything in your hot little hand or touch it, it doesn't belong to you. That gold of yours in the Bank's safety deposit box? That belongs to the Bank. You want proof? Just try to get it out at midnight when the Bank is closed.
