It would also seem worth pointing out that when all of us airside workers have these wonderful ID cards, there will have to be scanners/readers at all airside locations to check us in/out.
Oh no there won't .. that's one of the points to objecting ...
The new national ID card will have nothing at all to do with your airside access .. you can quite happily leave it at home, you don't need it for your work and it won't be asked for/required.
It's simply that airside aviation workers have been picked on as an easy group to coerce into having it.
By making it a condition of being allowed airside access to have a new National ID Card (even though it won't be passed or/used to to grant access) it means you have to get one or give up your job.
