Would the UK go back to imperial money as well? The system of guineas, crowns, pounds, quids, shillings, pence and farthings is really well-suited to the feudal system that Rees-Mogg and Johnson seem to admire and want.

Would using imperial money let merchants do dark patterns better? Like the USA pricing gasoline to the mill, $4.499 feels a lot less than $4.50.
