I know what you're saying but my point is that in any sort of society or group of people, there's a need for leadership. We're hard-wired that way. Even in the animal world, there's always a pack leader.
And as they say, power corrupts. So even if you took a bunch of peace loving hippies on a commune, eventually someone will bubble to the top and declare a need for leadership. And given enough time, they will attempt to enforce their will at the expense of everyone else.
Government is simply a form of it. Getting rid of governments would only result in another form of control or hierarchy which would eventually manifest itself in the same manner.
Or, as in your example, if there was no government, T-Mobile just might throw you in a T-Mobile jail for not paying your phone bill. In this case, the government prevents that from happening since that's not in their interests. They want to throw you in jail for not paying your taxes
