Copyright is codified as a law. From the moment something is codified as a law, it really does not matter whether it is ethical or not. The only thing that matters is whether you wish to remain legal or not, and before taking the stupid decision to not follow the law you must consider your power in relation with your government. They have an army and a police force to enforce their laws. If you are their citizen, then chances are that you could be liquidated quickly in case they get angry with you.
Copyright sets a way to copy legally. You just have to ask permission from the copyright holder. So, in theory everything is easy, you just email the copyright holder and depending on the anwer you know what you can do. But in practice it's extremely hard, because a copyrighted work may be orphaned or its copyright holder may be too stubbornly risk-averse to allow distribution even though such distribution would not damage their income.
Therefore, the copyright law seems to create some practical difficulties in using orphaned works or in getting permission from irrational copyright holders. This means that the law should be fixed.
In democratic societies your government is elected by you, so you have an easy way to change the law. Just find a politician that agrees to change the laws according to your liking and vote for them. If there is no such politician, just set up yourself as an independent candidate or start your own political party.
Of course, doing all that may not sound easy, but who told you that life is easy?
But just because changing the law is hard does not mean that you should not follow it, because such an action would mean that you would be considered a criminal by the legal system. So, it really is much better to fight this through politics and elections rather than through a cat-and-mouse game that could cost you your life or your freedom. Even if you consider the law unethical, you must still follow it because you are a citizen and bound by the laws of your jurisdiction.
