The rules and complexity is a big part of the problem, even if you don´t believe it is a deliberate scam, imo.
Wouldn´t it be very easy for a layman, to look at stuff like Fractional-reserve banking as just that: Magic money, that makes his money worth less?
They can´t give an explanation he will understand, neither will he understand why he isn´t allowed, to do the same thing.
Make the rules clear or change them.
