I'm a bit confused here. Are you saying that people should not vote, because democracy is only a local optimum, and that's not good enough to lend legitimacy to?

But there's no quick and easy way to get to nonlocal optima. Democracy is a strong local attractor. If national voted participation dropped to 15%, it would be likely to spark debates on how to reach out to more voters, whether more people could be engaged if the process were made more convenient, etc. It almost certainly wouldn't lead to discussion of whether we needed to be trying out other systems of governance.

If there's some other thing you mean, I'm not getting it.
