Moral of the story; You have to help people help themselves, and while our 'success' with my father was brief, sometimes people just resist treatment, and have real problems.
I definitely agree with your conclusion. The thing is, the government can't really stop people from doing what they're determined to do, especially if they're addicted. Prohibition didn't stop drinking to excess, legislation hasn't stopped drug addiction and making it harder to gamble won't cure that addiction, either.
