To many folk are so used to paying by card they think cash is a nuisance, just wait and see what might happens if the government introduced a CBDC, then say you upset a benevolent leader, and your account was frozen. Like the Truckers of Canada.
What you "cash" evangelists fail to grasp is that you are all paid through your bank, so your money is already in the banking system before you get hold of it.
How the f&!k does it make sense to take that money out of the bank and only exchange it hand to hand, and then go around believing that you're beating the system?
If the system wanted to beat you it wouldn't let you draw the cash out in the first place - you don't realise that you're just whipping boys for the conspiracy theory brigade. It's the conspiracy theorists who usually quote the Canadian Truckers banking freezes.
The truckers started their protests against the requirement to cross in to the US only if you were vaccinated. This protest then got hijacked by the conspiracy theory brigade and moved in to a much wider general protest about Covid restrictions. Part of the reason for the freezing of their accounts (and it wasn't that many people that had their accounts frozen) was because of the influx of funds from anonymous sources helping to fund widespread insurrection (AKA terrorism) against the Government and the anonymous funding of protests about covid restrictions.
We have similar legislation already in the UK to prevent funding of terrorism - so if the Government want to use it, they will.
The only way you're going to get anywhere near close to living in society without CCTV, ANPR, Digital Banking, Privacy Laws, government mandates and so on, is to buy yourself a plot of land, grow your own food, pull water from your own well, dig a cesspit, take on wood whittling as a hobby, gather fire wood to cook.
Off you trot, back to the dark ages.
