1) you will only need an aimpoint battery every few years so there is not much of a supply chain required
2)
A) there is no particular evidence for this;
B) you're eliminating options on the basis of a guess
C) you're ignoring the many advantages of various optics systems because the batteries will one day fail. But until that happens, which in the case of aimpoints may be YEARS, anyone who puts the optic on has a major advantage. And considering having an aimpoint does not obviate the possibility of having irons, there is ZERO disadvantage to having an optic. There are only advantages.
