I actually agree with you, De - although I deliberately didn't make that argument with my initial post.
What could be better than "private banks with no government regulation" (however he said it) competing with different interchangeable money? Simple: a physical base which makes it a slam-dunk to send them to jail for GROSS AND DELIBERATE FRAUD if they try to get funny.
The other thing, of course, is they shouldn't be allowed to hide behind a corporation, nor get excused in bankruptcy. If they don't have the metal, nail them with iron.
Corporations as they exist are SUCH a stupid idea. Fictitious entities should NOT have more rights than human citizens. Once you go down THAT road, endless criminality and shenanigans, as borders are tested and stretched, are guaranteed.
