What's wrong with gambling? It's people's own money to do with what they please. It hurts no one but themselves.
Ask the woman whose husband has blown the family paycheck in Vegas.
Ask the families destroyed by above behavior.
Gambling is not mere 'entertainment' - it is the encouragements of the LIE that one can succeed without hard work - to many in our society this is like crack cocaine - once they start they can't stop.
And no, they don't just 'hurt themselves'.
They hurt their families, their friends, and SOCIETY, 'libertarianben'.
As far as drugs go, I have a solution:
1. Mandatory execution of all dealers;
2. Mandatory incarceration for all users.
Oh, yeah. This DOES take some effort of the National Will. The imposition of which is OBTW, a positive factor in our national health.
