Okay...
Firstly, I said civilians seemingly weren't affected. They know aliens exist, and by all accounts no one cares. Even the kid from Iron Man 3 has a 'meh' attitude. If none of those people care, it does negatively stamp on the concept of a 'shared continuity' because NO ONE should be that blase about parts of New York being trashed by robot alien thingies.
Secondly, the assumption is they kept it contained to that pocket of New York. But even if they had, it still got absolutely trashed. And I don't recall seeing any Avengers doing clean-up either.
Thirdly, until BvS we cannot gauge the follow-up of the attack. Because we don't know whether that Lex's platform, whether that brings Bats/WW into the film etc. While they should have put more into MOS, that's hindsight thinking.
Finally, if they go the 'New York got screwed' route it provides a logic for Hells Kitchen looking like a Miller comic. And why they'd look to Daredevil. I mean currently The Avengers exist, so there has to be a reason for Matthew Murdock to feel like Hells Kitchen needs a protector. Granted that makes me wonder why The Avengers don't go in and save the day, given they're meant to be heroes, but he... the MCU has plenty of 'where are they?' holes as it is, what's a few more?
