At the risk of being banned for straying too far from aviation, the spectacularly mis-named Child Support Agency was given the power to cancel driving licences if they believed - often wrongly - that an individual was not paying what the CSA said was the correct maintenance. That is the problem with putting too much political power into the hands of monkeys, and allowing an 'infraction' in one area to have ramifications in other, unrelated areas.
Now, quickly back to aviation. An ID card will have a negligible positive effect on aviation security, regardless of whether or not it works. But it will have many negative effects, not the least of which is unnecessary cost for the sake of Gordon's political vanity.
