I'm assuming this is a joke topic of sorts....you may even be the first on this board, so gratz on that.

If serious, nope. TKD is better than nothing, but many many other things are better than TKD. Granted, the old "teacher > art" axiom obviously applies, but generally TKD tends to be for semi-contact point sparring, as opposed to all out fighting, and point sparring doesn't exactly help in a real fight. I actually fought a TKD practictioner in college (dont remember what belt...he wasn't black, but it was one of the higher ones) and beat him with relative ease. TKD has a few gimmick kicks that, if landed successfully (a VERY big if), could end the fight, but they generally tend to be very easily avoidable. And TKDs hand skills and grappling/submissions skills are EXTREMELY subpar. And hand skills and grappling/submission skills are FAR more useful in a fight than kicking in almost all situations.
