I have the potential to harm people near me.
Near me is context.
But, what if there is no one near me. What if I am 10 miles from the nearest person and threw the rock? And I am in a building and there is no living thing in 2 miles of me save me.
You aren't showing that it is true without context, you are just showing that to you the context is irrelevant. That's not the same thing.
