The estimates of problem gambling are on the order of 3% of the population. I think millions of people constitute "many". YMMV.

If you go bankrupt, that is society bailing you out. We cancel your debts and let you go free of them.

We also won't let your family starve, we'll pick up a chunk of your medical coverage, and you'll be consuming all sorts of public goods without paying your share until you're back on your feet. If you ever get there, because gambling addictions that go as far as bankruptcy can be devastating personally.
