I was debating writing a book, but the more I thought about it and the appropriate name for it, I'm wondering it you are writing it or would write it😅 "Fixing Money" People don't understand systems. We need a book that takes systems like Bitcoin and compares it to Gold and other existing financial systems of today including ones that work and ones that do not based on fundamentals like you mention in the OP. Lightning is the equivalent of Banking settlement and transfer relationships. Liquid is the digital equivalent of Hawala which has a place. People don't understand this because they don't see how it all looks at scale. People get all up in arms about the dream of P2P electronic cash but they don't realise most people don't care and they just want things to work. that will require developers and service providers on a sound money that is simple on the base layer and isn't compromising for somewhat arbitrary features. If we're engineering a new car, let's keep the parts that work based on historical experience. As the market evolves we will eventually find out how many demand certain solutions like custody with less counter party risk etc. We currently don't even know how many will desire certain things because money is misunderstood as it is and the few that are in it now are clearly different than your average fiat minded person. Other ideas: At scale, no one will ever have a L1 Hot wallet. Phoenix is cute but it's silly to run a bank from your phone that shuts down every time it's not running. I could go on and on, but I'm sure you understand it even better than I do. There are also missing pieces like a delayed settlement and credit system that allows for people to but things and a trusted third party to handle disputes from both sides like Visa. People will need to get used to seeing the fees associated with services because nothing is hidden like the systems of today, but the fees are lower overall. People spend time developing solutions that are only a transitional problem instead for designing for when every sat is a dollar. Would you write this?
