Don't forget that after WW2 America was able to hold these agreements. Only after passing from generation to generation have we seen corruption slip into the system and deteriorate the stabilizing ideals.
If we had strong politicians who cared about the ideals, bitcoin would have never of been created. There would have been no need to doubt the trust in government, but this is idealistic dreaming and not connected to reality.
This is why we need a systematic approach like bitcoin to remove the flaws of man/politicians and put the real price into our choices and purchases.
