I agree, but of course the people who argue against cash on convenience argue on the grounds that using cash you have to carry around different denominations, risk losing it etc.
My belief is that the biggest weakness of a solution is generally a side-effect of its greatest strength, in this case the need to carry around cash in different amounts and risk losing it, having it stolen are necessary in order to have something so easy to exchange among people.
