Sounds good but it'll be ignored - they won't care about public perception, they'll shape public perception, create it. 

They'll start with anyone on benefits. Then they'll champion restricting certain payments for lottery, drink, gambling at. People will cheer for it, because why should people who don't work have nice things, right?

Next they'll start insisting that state employees then contractors accept it. They'll have no choice, they'll be strongarmed in to it. 

They'll let the process grow gradually from that point on, no sense rushing it. It'll be just like the switch from cash to contactless again...people will resist then, but by bit, for one reason or another, they'll give in. 

Eventually you'll have to pay your taxes using their shitcoin tokens. It won't mean much by that point, since the £, digital or not, will be circling the drain. But still, they'll make you pay.

The only way out is resistance.

COVID showed us how powerful they are and how the vast majority will do as they're told, when they're told, even to thier own detriment.
