It’s discrediting valid concerns against card-payments. It’s invalidating how great cash is.
It’s when the worst person you know makes a good point.
And things now are so Culture-Wars-y, nobody makes solid analyses any more, that when the far-right say cards are bad, everybody jumps to thinking cards are good.
You do realize that cash self checkouts exist? They’re only rare as they cost more money for companies, but who says they couldn’t be legally enforced? I’ve honestly seen them only in hipermarkets like Auchan, Tesco, Le’Clerc and Carrefour.
