You're just frankly uninformed.
Shaving waivers have been so abused it's a running joke in the army.
It's still trivially easy to have a doctor get you a waiver.

Also, I don't even think they are necessarily abused. A lot of men are very sensitive to shaving, with degrees of sensitivity. I think there's probably plenty of guys who have perpetual razor burn and ingrown hairs and nobody cares.
The reasons grooming standards are enforced are the same reasons anything is enforced.
