SHIELD causes more problems than they solve. The same can be said for ARGUS, as well as the DEO. A lot of the time, we have these organizations in fiction that are supposed to help protect the world and keep it safe. However, instead they make things worse. Also, they spend a lot of time going against the main hero of the story, usually to everyone's detriment. I honestly wonder if they exist to be an indictment of government interference.
