I get where you're coming from, and I do like the idea of a self-contained centralized physical currency powered by whatever kind of tech, but I think the minimum viable money is much, much larger than the scale of your initial announcement/launch seems to indicate you think it is. The Monopoly example is interesting, because there's enough currency in the box to pick up the entire system and operate it. In that context, the money isn't the point, it's just a tool to operate the Monopoly game-system. Similarly, for us money isn't the point, it's just a tool that powers the human society-system. I think it's better to frame it in terms of the minimum viable society. Figure out how much system it takes for an arbitrary group of humans to operate a society that is indistinguishable from any given slice of modern life, and then derive how much new money you'll need to make and distribute to make it possible to switch all at once. Privately owned or rented homes, food purchased from a store, utilities, transportation, entertainment; all the things that being a human in society entails. All of it needs to be present and purchasable with the new money, or else the new money will have to be converted back to traditional fiat, which as many have said defeats the purpose and introduces a boat of security problems. I like where you all are taking the concept of money, I like the Kong experiment, and I wish there was One Weird Trick to get past the adoption phase and into usefulness, but idk it just seems like all we have are ten thousand interesting experiments.
