Yes, I think it can be justified for your media reasons 1 and 4, I remember some games that had such bad DRM pirating them was really the only way to play them.
Extra note, in the case of 4 usually you only found out about the terrible DRM after you bought it, and if you pirated it you should still have a legitimate copy of it, as for me, that's like getting extra copies of something you already own (that you will not redistribute) in case one of them doesn't work, which I think in some cases isn't illegal.
