Helgard, you didn't give the sources for your research, but check into the copyright forum and do a few searches on your topics. Many of your points have been extensively discussed and documented. Your conclusions are partially or wholly wrong in several instances (e.g. clothing, buildings, celebrities, real world items). The other point to consider is that somebody who thinks they've been ripped off or injured can still sue you, whether or not you think you're right, whether or not you think they have any rights in the matter.
