I have a strong dislike for positions that are absolute, and this discussion is a good example. “I don’t make intersection takeoffs….”? Even if the airplane is light and the intersection gives 5,000’ of runway beyond your needs? Even if not taking the intersection means crossing an active runway twice, once while taxing and once more on the takeoff roll?
I will turn down an intersection departure if there is not a generous performance margin, including obstruction concerns. But otherwise, why not? A smooth flow of traffic is in and of itself in the interests of safety, a fact too many pilots (and all airline management) fail to consider.
And as already pointed out, the “altitude above you” can kill you if you go into the coffin corner trying to get there. And the “fuel in the fuel truck” may be the best place for it if it was beyond your needs and you now find yourself with one shutdown and mountainous terrain to climb through.
We get paid to think.
