"like complaining about the quality of a highway once they intentionally break through the guard rails" Your metaphor brings to mind an image of someone who can see the guard rail, and then deliberately chooses to expend quite non-trivial effort to break them. This is not an accurate metaphor. As I'm not in the metaphor fix-up business, because I believe they tend to mess us up in precisely this sort of way, let me simply directly point out this gets it backwards. The default is that you will write a program shot through with undefined behavior, and you must make quite substantial, intellectually-challenging efforts above and beyond the intellectual challenge of writing something in C at all that at least sometimes works, to write your program in a way that doesn't have UB in it. It has no resemblance to driving down a road in a normal fashion and then bashing guard rails down.
