Well if we wanted to stop stockpiling (not saying we should) simply make it impossible to be 100% protected from covert ops again, that did a pretty good job of discouraging too much stockpiling....

Seriously though, I really think this is a non issue, as several have pointed out it is simply another strategy available in the game, which has it's uses, so there really is no good reason I can see to try and discourage it.
