ATM's in the Netherlands cap at 50€ (so any higher denomination must be requested at the bank), due to people using contactless payments frequently there's less incentive for cash. Even then, why did the EU decide to print 100€ or 200€ notes (forget about a 500€ note as they've stopped printing more since 2019 but it is still legal tender). Stores refuse to accept a 200€ note for a 150€ purchase, why do these denominations exist?
Because other countries handle that differently than the Netherlands?
e.g. In Austria a not insignificant part of people exclusively do transactions in cash (think of that what you will). There even was a push to anchor cash payment is the constitution, so removing 100/200€ notes is not even on the table
