If you do, sure. But nobody has that ability. I just mentioned, elsewhere in this thread, a couple major players in the cryptocurrency space who have proved to be untrustworthy. And a lot of people got burned in part because they believed the hype that removing the need for trust from the management of the "physical" currency is equivalent to removing the need for trust from the financial system itself. That might have been true thousands of years ago, before the birth of finance, when everything really did run on just cash. Things are more complicated than that nowadays, though. Cash is such a small corner of the money supply in a modern economy. A few percent of the bits that people bother to try and count, and there's a lot more that goes uncounted. A distributed trustless public ledger for the cash doesn't really help with the trust issues for that stuff. Frankly, it only helps with the small subset of money for which I'm least worried about trust.
