[Captain America: Civil War] What happens if all the avengers said no t the accords. What could the government actually do to them?

I mean we saw what Cap and Bucky can do to hit squads multiple times, Ironman can literally make an army and we have seen with Jarvis before that he has the means to hack all of the U.S Nukes if he so wished, Vision is basically indestructible and as seen in his fight with Ultron he also seems to have the ability to hack on a greater level then Ultron and so again THEY CAN CONTROL ALL THE NUKES! Or pretty much all the Internet and online information networks. 

Thats not even getting into all the assassinations they could pull off with both Black Widow and Hawkeyes, the brainwashing they could do with Scarlet Witch and heaven forbid just imagine what would happen if they had a Hulk as well as Thor and the allegiance of Asgard.

So again I ask, what could the government actually do if the avengers had said no that wouldn't end terribly for them if the Avengers felt threatened enough to go full force against them?

The government could take away any semblance of a normal life any of them would ever have.  Tony wants to go to a club? nope he's constantly on guard that a government team will take him down.  Scarlet Witch want to visit her brother's grave? That place is under 24 hour surveillance.  Steve want to go grab a beer with Dum Dum Dugan?  Better be in a secret bunker.  Hell they couldn't even have homes.  They'd live like the Winter Soldier did in shitty apartments with go bags always ready.
