In your opinion. Mine is different. Hopefully you don't find that insulting.
Wrong "I" word. I don't find it insulting, just curiously and appallingly ignorant.
I was twelve years old when the original AWB was passed. It was very influential to me, and was the single driving force that catapulted me into the gun control debate. By the time the bill sunsetted in 2004, I had lived almost half my life under its shadow. Forgive me if I'll spend most of my current time trying to get my hands on as many of the things as possible. But somewhere along the way, I discovered they are fun, and a large piece of me enjoys pissing off all those who say I shouldn't own them.
Now, I also just finished playing the new Call Of Duty, "World At War," through for the first time on one of the harder difficulty settings. I must say, I liked rocking the AK or G3 in Call Of Duty 4 more. But my interest in FPS comes from my interest in guns in general, and my preference for FPS with realistic weapon modeling of modern assault rifles comes from my preference of those rifles in real life, not vise versa. So correlation does not equal causation, and in fact, assuming that most or even many of us only like modern semi-automatic clones of military assault rifles because we've seen them in video games is actually bass-ackwards and 180 degrees from the truth.
As for the OP, the practical side of me says that even without a real use for it, if you had bought the LMT, you'd likely be able to sell it for a healthy profit in ten years or so, and in doing so, find your way into several other guns you'd find more enjoyment or use out of, provided you didn't fall in love with the thing and end up with about a dozen different uppers for it (that seems to happen to some). So in terms of actual investment, I think the LMT makes more sense. However, if you are more into immediate gratification, and find more short-term use from the firearms you did purchase, then more power to you. I am sure the LMT will find a nice warm home anyways, given the current political atmosphere. Everybody wins.
