Well what we don't hold is pieces of paper that can easily be stolen, & burnt. Or pieces of metal that can easily be forged into a cutting implement for troll removal.
Our trade consensus & storage of value is far more secure, far more difficult to grasp, as you clearly demonstrate, & therefore far more difficult to snatch at. You will see the light some day, padowan. You will stop reaching for grubby materials & accept the might of the capital idea

Yes, a car can be stolen, a house burned, land confiscated, a lottery ticket lost. But in the Bitcoin scheme, non of that can happen because there's nothing to steal, burn, confiscate, or lose. You have nothing. You enter a chain distributor scheme, supply an old participant with resources, and then wait for a new participant to do the same thing for you.
Right, willing participants, so you are beginning to conceive of the idea of consensus & why the trust relationship inherent in economy as we know it is superior to anarchy, banditry, feudalism & barter. So once you get your head around the real nature of capital exchange, that it has very little to do with pieces of paper & metal, & everything to do with tacit agreements & social contracts that consent in good faith to a system of value exchange, you might now start to understand what decentralization in the internet age means, & stop wetting your bed because your banker daddy isn't going to carry quite the same social mystique he once did. Things improve, people exploiting the old ways lose out, get over it.
