The talk about "trust" is also problematic from an empirical point of view. You see plenty of people who loudly proclaim that they don't trust the government / the Fed / any official institutions, yet you seem them using the currency provided by those institutions. Clearly, trust is not what gives the currency value.
Granted, those people may not have their savings in assets denominated in that currency (if they have any savings at all), but - in line with what you write - investment decisions shouldn't (and rarely do) have anything to do with "trust". Consider that security-thinking folks more or less define a "trusted person" as "somebody who can undermine your security".
