That is one long post
Lot of categories.
Taking first category as totally honest and last as totally corrupt, I can't help but feel that most people fall somewhere in between.
Not only that but individual attitudes, ethics, etc. can change quite often dependant on many factors.
My thoughts are do whatever seems right to you. If it seems right, there should be no need to justify it by saying you were forced by others to take this path.
If your children are hungry then by all means steal bread, and if restrictions or DRM force you into piracy because there are no other interesting books available for you to read well do the same thing.
I am not a totally honest person and while I wish I were, I do try not to make excuses to myself or others when I am in the wrong. I also try not to brag about it or lead others to do the same although I have not been entirely successful on either point.
I can totally understand stealing ebooks, I just can't think of a single reason that makes it a just or noble act.
