I’m pretty happy with our “no murdering” setup, even though it makes some people happy (in the moment).

IMO there’s plenty of room for hardline stances. Who cares if gambling goes to the black market? There’s a black market for every serious crime - doesn’t mean we should just okay it. And I’m not sure the USA’s halfhearted only-for-the-poor prohibition is proof that the concept of banning things is broken; if it proves anything unrelated to capitalism, it proves that you need societal buy-in and continued, consistent government pressure.
