Maybe this confusing can be resolved if you view the authority, spammers, and "armed men" as equals. For example, you can treat them as interest groups, but with different level of power. It's a game, it's about incentives, desire, promise and payment, nothing about "do the right thing" or "for the people".
Now it's the Armed Forces got the top power, so you obey them until either they get replaced, or your own power grown so you don't have to continue pretending. The rule is just that simple.
And on the referenced "Civic Hygiene" article:
> But! Shock horror! After creating the database, the Government loses the election and the homophobes at UKIP get in to power! Now they have a database of every gay in the village, and can harass then, try to "cure" them, or make their lives a living hell.
Then, you just get cured ;) It's like a magic. Previous day you are a guy with a deeply lovely boyfriend, today you are seeking to marry the most beautiful woman available, because the cure they give you make you realized how disgusting the hairs on man's legs really are, ew! puke! Just lie, everybody can do that. Truth only belongs to people you love and love you, not the people who don't care about you, not even the neutral public.
BTW: Completely off-topic here: There was an article titled "Incentives are for losers" posted few weeks ago: https://news.ycombinator.com/item?id=49227652. It was beautifully put together, the leftist part of me almost convinced.... But, the rest of me realized that if you look the real "successful" people out there, the rich and powerful etc, you'll found that they all succeed by chasing the right incentives. Interesting uh?
