"I have successfully privatized world peace"
The Senator: Our priority here is to have you turn over the Iron Man weapon to the American people.
Tony Stark: Well, you can forget it. We're safe. America is secure. You want my property? You can't have it! But I did you a big favor! I have successfully privatized world peace.
Who doesn't, who can't understand the magnificence of Stark's reply? It's his property, and to hell with tin-plated gods who demand it on behalf of "the people." And even though every other human on the planet would be free-riding, Stark was still willing to use his property to achieve world peace -- and more successfully than the state, he pointed out.
