Bitcoin exists. Completely permissionless, anyone on earth can use it. Easier to accept as a merchant than any third party integration. Doesn't require you to trust any government at all.
People are downvoting you, but I can literally pay for my meal using CashApp at a diner in the middle of nowhere using Bitcoin.
Unfortunately it's also pretty clunky for tax reasons in many places and inherently deflationary (and as such problematic from an economic point of view).
Sure, great if you don't trust your government or whoever issues your local currency, but if you can, there are better alternatives. Trust is an asset, not just a liability.
Cool, but unfortunately, it has the same same drawbacks as cash. If you get scammed, accidentally pay too much or lose your wallet you will never get it back. I sleep safer knowing that there is some protection in the banking system against losing money all of sudden.
