care to prove he's wrong?
how would a barter society be better than paper currency. please, provide historical and mathematical proof for your bogus hypothesis.
Have any paper currencies stood the test of time? Any at all? nope, all of them have failed. While barter still lives on.
No one said that a barter society would be "better". better is subjective, apparently to you the continual erosion of the currency's purchasing power is your choice of "better" for you.
