Someone claiming they created something which I created is the closest to harm on that list. Fraud should be punished.
The others aren't harmful, unless you're defining harm to include the loss of something which someone believes they are entitled to, a concept which is fraught with problems.
Creating an image (or any non-physical creation) doesn't obligate the world to compensate you for your work. If you choose to give it away by posting it on the internet, that's your choice, but you are entitled to nothing.
Let me define a few cases of 'uses that image' and see where your line in the sand drops
* If someone used that image as part of an advertising campaign for their product, they are profiting off your work. Are you not harmed?
* If someone used that image and pretended they created it. Are you not harmed?
* If someone used that image and sold it directly. Are you not harmed?
