if there was a way to counterfeit money that was 100% undetectable, and you had 100% no way of getting caught, i'm sure a lot of people would do it. if it was easy of course. as in clicking a couple buttons
Pretty sure that in that case the economy would go to complete shit and the entire concept of money would have to be reworked, but whatever. And in that case you'd actually be devaluing the currency as a whole, making other people's money worth less. Which might make it some sort of regular theft? I dunno.
