You've filled me in on a few things a bit better crypto-wise, though I still feel many of the problems still exist. It still seems assets would either be easier to sieze vs cash or more of a liability to store on one's own. I imagine if it were to become an official currency, some more protections would get out in place, but that would probably compromise the anonymity of you were to make a claim about it.

While you can't look at all of a bank's ledger, there is still redundancy and a known route to clear up discrepancies and fraud. Benefits of traceable currency.

I'm not super techy, so I don't know if man in the middle attacks are still possible or other methods of intercepting transactions.

It didn't seem like a good idea to go back to things like the drachma, but I get why people would want it. Again, I think the blame gets placed in the currency rather than the things that lead to that currency being devalued, but that's another story.

We also didn't just print money thoughtlessly. I didn't agree with all the choices the Fed has made, but overall I think they've done ok, but it's not as though we can examine how the alternatives would have played out.

These are all things we could debate endlessly of course. I can't ever see a government giving up control of currency though. That's just too big a thing. I try to stay open to useful cases for crypto too, but most proponents just seem so off-putting.
