The same thing is going to apply to every other sphere of policy. We on HN believe that tech privacy is important and follow the developments on this website, but it's a stretch to expect regular people to know this stuff. And it's not a knock on regular people! They're experts in their domains, everyone is - from car mechanics to baristas to hobbyist knitters. People are too busy resting from work, taking care of their families, and pursuing their interests.
So where do you go from there? If you're engaged in the policy world, it helps to create institutions regular people can delegate policy expertise to, like the EFF or the Humane Society. Intense lobbying by small groups gets results (in both good and bad ways). And having a large "laity" of people that support the institution and expect it to do the nitty-gritty is ok.
