Governments and top bankers are desperate to outlaw cash.
The reasons are simple -
1) Every transaction you make can be checked and audited.
2) When the next financial crisis hits there will be no more bank runs as there will be no cash to withdraw.
3) When negative interest rates hit you wont be able to stash cash under the mattress, your money will be locked in to a bank account becoming less and less daily.
4) When a bank folds they hold all your wealth and you know who will end up paying for their failure
A cashless society = 100% bankers/government financial control over you. Not a "good" citizen, then they freeze your account leaving you penniless.
Anyone who supports scrapping cash and moving fully to digital currency is an idiot that doesn't fully understand the implications.
