Eliminating the 50£ and $100 is just a sad joke
The worrying thing is simply that it's in the State's interest to have every monetary transaction be electronic and thus entirely traceable, also in aggregate; whereas it's in my interest to be able to spend (or loan, or give away) my money privately.
