Cashless populations are much easier to track and control.
Cash is not only anonymous leaving you unidentified as a party making a transaction, but cash can be stored in a mattress or a safe, hiding what you are worth from the government.
Once they ban cash and require some form of electronic money transfer, then not only can they track every transaction, but ultimately they can control it. They will know exactly what you are worth and they can kill the underground economy — which is good and bad. I want illegals aliens to pay their taxes and a no cash system will make it so they can’t hide that money anymore — but I don’t want to lose my freedom in the process, and that is just what will happen. I would rather illegals work under the table than that I lose my freedom.
Either way, cash is going away. The government demands to track our every move and they can’t track cash.
It also makes it easy to take everything for a bail-in to try and save son big banks.
