Tony Stark isn't Bruce Wayne, but he almost always has a plan. If there's some way he could go through all this and (a) come out alive and whole and (b) keep the secret IDs safe from Norman, he would have done it. Even Matt Fraction said there was a reason Tony hadn't thrown himself into a volcano (IIRC).
Stark Tower (why hasn't Norman renamed that?).
This might sound odd, but maybe Norman had some respect or admiration for Howard Stark, which is why he didn't rename Stark Tower. Before he went "Goblin Formula Gonzo," Howard Stark was Norman's role model in business. Just an idea.
Finally, the SHRA Database is gone? This isn't exactly "handwaving" CIVIL WAR, but it's close.
