And when you have cash, a single robbery can destroy your life savings. Or police can come and seize your money. There was someone in the thread amazed about the trust people put in the complex stack. I'm amazed the trust people put in the ordinary paper-based process. A computer cannot be bribed and leaves a cryptograhic audit trail and does not burn but for some reason a stack of papers under my matress is more trustworthy. There is a lot of irrationality around the topic. I don't know who's right but very clearly it is to an extent about fear of unknown.
