I just rewatched Civil War rn.. and yeah I think the way Tony wanted it wasn't for the Avengers to be the UN's war dogs or special world task force
But he did want a bit of oversight/regulation in order to keep them in check and not running boundless
Bros trashed NY and Sokovia albeit collateral damage for saving the world but they destroyed NY and drop an entire country down from the sky and left the world to pick up the pieces
BUT Steve did have valid points about agendas, how slow it would take for "approval", and not letting them be where they need to be or not etc.
Steve still a scumbag for free loading off Tony while knowing his lover killed Tony's parents in cold blood tho
