With easily I mean humanity does not face a direct threat from it. It's the crooked government that's culprit of devising the fiat devil. I'm not saying that "abolish the govs", I mean the restoration on governments or fiat money can be done more easily than it can be on the options in the poll.

Fiat money will not easily be overcome just because it is such a potent power projection tool of nation states- and if you think nation states/governments will be dispensed with easily I say that is wrong. People - most people  will clamour for government if there is none.

Government is fundamental to peoples security and wealth- yes there is a lot of bad government but without government people are even worse off.

If you disagree go live somewhere there is no government and see how you fare.
