All money is the same. It's all non-physical. You can't eat it. It of itself won't protect you from the rain. Or from malaria. What value bitcoin has is not derived from there being 21 million of them, or from the network being decentralised, or from some other such seemingly objective feature. Every little bit of value bitcoin has is derived from people agreeing with each other that it has value. Pure agreement. That's it. Which is true of every other kind of money, past and future. Trying to assert that Bitcoin is somehow more real than other types of money is silly. It's my imaginary horse runs faster than your imaginary horse. It's my pokemon is stronger than your pokemon. Whichever money is the best at facilitating agreement will be the most valuable. That is until people decide that they don't want to agree with each other anymore. Which they always do decide, sooner or later.
