This has spun into an interesting discussion of SD vs. sport. I think it's shortsighted to be too far on either side of the issue, as TKD has much to offer for both. Yes there's a difference, but I think we make too much of it.
What is required for effective SD?
--situational awareness and an understanding of how violence develops
--appropriate response process(verbal skill and legal awareness to be defensible and avoid violence when possible)
--effective skill set to stop assailant(s) (good techniques on good targets with power)
--timing and execution under adrenaline/stress load
--ability to execute the above when tired, injured, overdressed, in mud or snow, etc.

What is required for effective sport?
--ability to read and adapt to opponents, including when to attack, defend or counterattack
--ability to work within rules to win, maximizing points, minimizing penalites
--effective skill set to score points (good technique on target with power)

timing and execution under adrenaline/stress load
--ability to execute the above when tired and injured

1. I'll agree that TKD doesn't cover all of the aspects of SD, but it does add a great deal to the mental and physical conditioning needed to keep your cool WTSHTF.
2. (Pet peeve alert
On the SD side, I think too much time is spent on physical technique without practicing the situational awareness, verbal skills, legal knowledge, and adrenaline reactions that round out SD. You can have a great hammer fist to Adam's Apple, but if you cause death or great bodily harm without doing the rest right, you will regret it forever.
3. I think TKD is good for personal growth. I don't think that takes away from people who participate primarily for sport or SD. Some of the sport benefits support SD. As practitioners and teachers we just need to be clear about what is sport and what is SD. You really don't want your 8 year olds practicing 'knife hand to throat' on the playground anyway.
4. I won't argue with anyone who wants to focus primarily on SD or sport--I too invest a great deal of practice and study related to both. The SD has real, perhaps lifesaving value. The sport is so good for my mind and body that it likely has life-extending value. Both are good.
Regardless of your focus, full contact sparring with unfamiliar opponents further develops resilience and challenges one to keep a clear head and adapt when hurt or getting beat on. I think that has value whether or not you ever set foot in a tournament.
