>True ownership is non-existent.

Why? The military power owns things by enforcing their ownership. This is, in fact, the true ownership.

You have to pay taxes to own land so the power which is on your side can prevent another power to re-own it.

If you don't pay taxes to the power which is on your side, why would it allow you to own stuff and provide free protection? Out of good will?

That's how the world works, ownership without the power behind it is non-existent, as well as power without the money behind it is non-existent. When there are enough powers balancing each other, stable systems emerge, and we all can enjoy some few decades of peace and prosperity.
