A cashless society wouldn’t happen in my opinion.
The world is just too corrupt for it. Everyone needs cash so things can’t be traced.
The elite need there pedophilia to not be traced. Etc.
But if it did happen SP would just get card machines. Many small business have them and there not hard to accuire or bank transfers would be option instead of handing over cash at a start of the meet just transfer it.
Anti establishment! Anti tax! Anti work slave lifestyle!
