It's a communist inspired 'what's yours is mine'.
Imagine person A using force to destroy or deny the food, water, medicine, and shelter that rightfully belongs to person B who legitimately purchased or created it.
Person A's actions could KILL person B, because food, water, medicine and shelter are necessities for and means of life.
To steal a person's means of life causing their death is murder.
I believe DEADLY force is fully and completely justified to protect what sustains your life and what rightfully belongs to you by creation or purchase.
Thanks for the information.
