The same argument can be used to build a police state. But I suspect that you’re not in favour that either.
We shouldn’t be building technical systems that “trap” people, just because they might be doing something bad and might want to prove that one day.
Additionally you’re also ignoring the whole “people have the right, to not have their emails stolen” argument. DKIM signatures are only useful if the emails are stolen, are you trying to suggest that it’s ok to steal emails from people if they’re bad?

No, just the opposite, that is an excellent argument and I think that the privacy should be the real focus when we discuss the freedom, and not the accountability. Because freedom is not to be able to get away for the lack of evidence, freedom is not to put innocent people in that kind of situation in the first place.
Police state doesn't come from the ability to track citizens, it comes from the lack of transparency and government's misuse of the information. Now, reality is that having more data collecting increases the chances of misuse, but I think we're attacking the problem from the wrong side. Rather than killing the option to track emails, there should be much more control and transparency on when and how that data can be collected and used.
