My definition of ownership ...
“You only own that which you are willing and able to protect by whatever means at your disposal”
I'm not responsible for what other people think. I am ONLY responsible for what I do.
There are those who deny ownership of their actions -- Baltimore comes to mind. And there are those who react so predictably to what others do, that what others do appears to control them, such as the MSM "controlling" people into mass delusions. But the reality is that each cognizant individual born has ONE possession that only the individual owns: the self, and how that self responds to what happens to it is the ONE, the ONLY, thing any individual really owns or controls.
