It's all true, but in practice it's difficult. And if it's very hard to use it, there's no network effect. Nodes and wallets are a tradeoff. If you're a Goldsmith, you are your own "node". If you build your safe with metal plates from the ground or buy one with cash only, there you have your "wallet". You could move to a place where people like gold. India. That would solve the network problem, maybe. In the past people (retail) dealt with all that stuff... the introduction of a necessary third party (government) standardizing coins was very successfull, no doubt. All issues above was kind of solved, network effect grew exponnentially with such a success, that the physichal mean (coin) became too value dense. Really enjoying your comments. Great provocation 👍
