It seems the governments have a very different idea of what those values are than the people. Until those ideas are aligned, governments are out to get the people. There is no point in any of this. Because ultimately, no matter what technical solutions you can come up with, force and law always trump those.
Perhaps at some point you could make the argument that we don't explicitly know what the government does and that's why it's doing it and getting away with it. That's no longer the case. We know exactly what the government does, we don't think that it's right, and yet we can do nothing to stop it. So either we need to overhaul government or accept the status quo and quit bitching about it or trying to create technical solutions to fix social problems.
If the government can mandate networks spy on computers, it can mandate manufacturers spy on users. As they are already doing this, fixing the network solves nothing. As for foreign adversaries spying on users, well if you are not in the US avoiding that is impossible as most of your computing experience is under regulatory capture by the US government.
