Are gambling addicts limited by time or by money? If they're limited by money then reducing the house edge just means they'll play more before going bust.

True. However reducing the house edge to 0 would mean that they can play until infinity without loosing money on average.

But then who would bother running a casino? You can maybe approach zero, but not achieve it.

Edit: also, I'm not sure if that's quite true. The possibility of going bust introduces an asymmetry that makes your long term expected value lower.
