If God truly made us, then God's Word is just providing information about our own best interests, the purposes for which we were made. Those who reject that Word - generally with the contempt shown by our libertarian brothers on this thread - also reject valuable information about how they themselves could most happily live. They have that choice, of course, but the rest of us are then forced to pay the bills for their so-called "freedom."
Just one example: In those places in America where libertine values hold sway over male-female relationships, the public schools are so chaotic and dangerous that decent people will not send their children to them. But they pay and pay and pay for them nonetheless. In fact, they pay more for them than parents pay for decent schools in more conservative parts of the country. And that's just one small example.
