The damage is already done by not enforcing "All merchants must accept payment by cash". By accepting that any shop can say "we dont accept cash", we have already lost that freedom to pay by a not easily trackable form. I wonder what more this law is hoping to achieve? Stopping that one guy who buys 10 laptops with a bag of cash? The merchants are already required by law to report any transactions above a certain amount made by cash.. so it is nothing new. If I sell my car on Marktplaats, I cannot accept cash? is that it?
