You can't send someone cash permissionlessly, near instantly, anywhere on the globe. Governments can just as easily outlaw cash... So, I don't understand how your argument against Monero doesn't effect cash even more.
Volatility can also swing in your favor, not just against you. You can also choose to swap Monero for cash, silver, gold, other crypto, or anything else of your choice. But those are all volatile versus USD anyway. Even the value of cash is volatile because of inflation.
You are the only one going on a tirade babbling about hitler and jews. What is your plan? To impotently beg your governments to please continue allowing cash for the rest of time?
