I found it a very interesting quote with regards to building trust onto a signature and that the more trust you have built onto that signature the more stupid it would be, to put it all at risk by defrauding someone.
And what CSW said about previous money and that the bills had the signatures of other people on it.
One of the problems of our current system is, that it doesn't have enough memory to store all those "frauds" in a reliable way.
We have systems, but they are being run by individuals. And those individuals will erase their own "shortcomings" and those of their friends out of memory, so that they will always seem trustworthy.
Blockchain may change this, since it has a very large memory and is really hard to cheat and moneypulate.
