Sure.
But if you go over to where a stranger lives and build a wall around them. You are responsible if they then starve to death.
If another stranger is delivering food to a different stranger and you kill the food deliverer. You are responsible for that mans death.
These analogies are much more relevant to the discussion. Isreal is disallowing people from delivering food and has even killed people that do (leading to organizations like word food kitchen to leave).
