Even if you do it, it's still not stealing, it's illegal copy.
So when you will "take" something from shop without paying it is not a stealing, its just illegal copy?
When I take something from a shop, this thing is not in the shop anymore, it's only in my pocket, so it's stealing. The models from FO3/NV are still here, so it's copy.And yes, this is important. From a juridic view as well as from a philosophic view.
So from law and philosophic point of view e-stores that contain music, games or e-books doesnt exist and are only abstract vitrual beings?
