> You are comparing people defending their own property to people stealing other people's property.

No, I'm comparing people forcibly, by way of the state, defining property one way and depriving people who disagree with that definition of what the dissenters see as their property rights to people forcibly, by way of the state, defining property a different way and depriving people who disagree with that other definition of what this other set of dissenters see as their property rights.

That you happen to prefer the capitalist model of property rights doesn't change the fact that it is imposed with state violence on those who disagree with it's parameters.

> Fortunately, humanity came to agreement about which of these two were acceptable at the dawn of civilization.

Humanity did not come to a universal consensus on a model of property rights at the dawn of civilization, and various models of property rights have gained and lost popularity in the intervening time with many (including as recent examples, but not limited to, the Leninist Communist model and the capitalist model) having been imposed through state force at various times and places.
