Expired ID's

I dont understand that you stop being that person once past the expiration dates. Why does it become a big deal? I really have never fully understood why people are so stringent on this, especially if its been expired for only a few days or so. I remember going to Vegas once with my dad for his birthday, and his drivers license expired on his birthdate. Couple days later, trying to board the plane back home, we almost missed the flight due to him going through all of these screenings and such. Is this the way it has to be?
