In the case of copyrighted books or research papers, it could be a matter of life and death for the user, if we are talking about access to various types of medical research, for example.
Research papers in medicine are written for specialists, who already have access to them by means of employment. I don't know how access to that literature can save lives otherwise. Even if that was the case, it is a very far fetched way to prove that you need generalized civil disobedience with regard to copyright law.
In a lot of countries in the world, medical institutions or individuals don't have enough money to pay for access to research and books (lib-gen, the sister project of sci-hub also serves pirated books). And I agree, that might not be a proof we need civil disobedience in general (with regard to copyright law), but I think it does show that copyright law doesn't work well for medical research. I think similar could be proved for other areas covered by copyright law, but that would be a long discussion.
