it's almost as if fraud is mostly a societal problem rather than a technological problem...

I think the underlying assumption that the "amazing transparency" enabled by crypto currencies will necessarily lead to a fairer more humane world is dangerously naive.

Does it not occur to people how an immutable, publicly inspectable ledger that records all your transactions might be abused by criminals and/or corrupt authoritarian governments?

Maybe HN is the wrong place to quote 90s rap songs, but these guys knew a thing or two about criminality and human nature.

Well to be fair, the reason we're having this discussion now is because people have been watching and questioning the expansion of the Tether supply via its transparent blockchain.

Someone could probably argue this is a step in the right direction from the days of Mt. Gox and its complete lack of transparency.

You mean the transparency of private individuals and organizations managing their own funds? Ok, let's assume, for the sake of argument, that you are entitled to and able to access that information and that it is somehow more available in _existing_ centralized systems. How are you going to enforce or even verify the degree of a centralized governance system's transparency? You can't. So your comment is somewhat deceptive, imo.
