> €50 notes, sure, but Europe is backwards - I saw a €200 note once when buying a ferry ticket
To add to your anecdote, on the Europe part, in a few years in Europe I've seen a few 500€ and 200€ notes (the last one a few days ago, used to pay a 1€20 coffee), and lots of 100€ notes.
This doesn't only apply to minimalists. I don't consider myself a minimalist, but I do consider advertising as a psychic attack. This is how many justify disabling billboards and ad blocking : they are merely defending themselves.
