And you are ignoring a much bigger issue. For instance, the Fed has expanded the USD monetary base by about 4 trillion in the past six years. So why not take that figure, divide it by the total number of transactions in the past six years and call it "the dollar's cost per transaction"?
Every inflationary currency system suffers from the same problem. At least bitcoin has a hard cap on the total number of units that will ever be available.
