And then US government prints trillions of dollars and inflate your savings. Or Russian government locks you USDs while Visa, Mastercard and sanctions make it impossible to move money out of the country. Or ask Belorussians and Argentinians how much they like double digit inflation that goes year after year after year while government limits ability to buy a more stable currency. Above is just about money but there is another perspective. Think about a car sale and how would you automate it. To date most car sales require some paperwork to register the right transfer. This happens behind the scenes and you may not know but it happens and occupies some people. You simply cannot automate a car same with just a database. There must be a trust component in the system and a way to maintain it. Trust maintenance typically means audits, licensees, etc and they do not come for free.
