Do you realize that the exact same argument can be made against honesty in government? "If you're honest, look at all the money in bribes you're giving up! Everyone does it, it's almost impossible to get caught and even if you do, it's a slap on the wrist. It's stupid to not take bribes."

And sure enough, everyone starts taking bribes. The corruption spreads to every level of government, because every individual makes the same calculation: take the bribe, more money for the family, don't take the bribe, less money.

Secrecy is a bribe.
