The advantages [of the Digital Pound] over cash are, then, as clear as day. The pesky thing about cash is that it isn’t regulated. If you want to buy something in cash, you just hand it over to the person who is selling the thing, and that is that. This covers the transaction in a layer of kryptonite as far as government is concerned: it can’t control who ends up owning the money, and it can’t control whether the transaction takes place. The digital pound, and the way it is being set up, offers no clear advantage to the ‘user’, but, again, that isn’t the point. The advantages are obvious to those doing the governing, and that is ultimately what motivates the entire project for reasons which by now will be well understood.
Highly recommended that you read the whole thing.
