It's a comic. Were all these points so absolutely implausible that they took you out of the story? Obviously they were, but really, why?
When there are too many convenient coincidences, yes it does take me out of the book.
Nothing was much of a bother until Iron Man showed up.
If this story took place in upper Manhattan, Iron Man's instant arrival would have been plausible, but instead it took place halfway round the world and it was like Iron Man was hiding behind a tree waiting for his cue. For Iron Man and the quinjet to 'plausibly' get there so quick, they would have had to be in the area and if so they could have just used their eyes to see DD in trouble atop the castles roof - making the whole plot device of the ID card meaningless.
