Tangible Vs Intangible Harms
You are right that theft, murder rape etc are harms which can be physically identified and their effect also can be time and resources limited. But Intangible Harms like Integrity, as u discussed, would do harm in a unexplainable manner. Humanity needs to learn that Intangible losses have catastrophic results and our society should eliminate this threat. This could only be achieved by NO HARM principle which is very much highlighted in this post.
