The very beginning of the article asserts that they're essentially the same. In a world with more than one person alive and interacting, it's true.

I disagree. There are many forms of power (including F*v) but what we commonly confuse is power that is the means available to accomplish a task, and political power that represents ones altitude in a social hierarchy. And though I agree with you that where two or more people gather together there will be competition over who is dominant (AKA politics) I disagree that those of higher social status can have %100 control over anyone. After we make our requisite displays of subservience to the overlords, we can still carve out a lot of freedom needed to accomplish our own goals, if we are smart and discrete about it.

The beginning of the article says the exact opposite.

In a sparsely populated world everyone can have their own place and do what they want. In a highly populated world that's not possible. People will share space and have differing views on how things are to be arranged there.

Even (and especially) in sparsely populated worlds, people have to share space. Look at Antarctica, the desert, etc.

The two are one and the same. If you have no power over other people you can't stop them from impinging on your own circumstances.
