Why do you assume I have to actually scrap a card?
Because when choosing the upgrade, before you get to the act of choosing which specific ones to drop, it says you have to pick upgrades to remove. How does the upgrade card get on the list from which "the player may then remove...", if that upgrade card doesn't exist in your fleet? The only flexibility imparted to this process via the "may" is that you don't have to remove ALL upgrades of that type (you might want to keep your Ordinance Experts, but drop the Gunnery Teams, for instance).
