> generally speaking, gambling more than a token sum (say, less than $100) should not be legal exactly because any benefits of gambling is far outweighed by the mountains of externalities it brings. Yes, this includes the obvious incentives to threaten random people. It's bad for society, so it should be effectively banned.
I agree with you in theory, but remember that people frequently do illegal things, just illegally. If we assume that people will in practice gamble whether or not it's legal, I'd rather the gambling not be run by organized crime free from the ability of everyone else to oversee and regulate. That would be the same thing which happened with alcohol during Prohibition and which happens now with the many illegal drugs fueling today's Mexican cartels and US gang networks.
> The only reason why it has suddenly become legal everywhere in the US is because many states have found themselves under mountains of deferred liabilities and are scrambling to raise revenues however they can without raising taxes.
And because of a SCOTUS ruling overturning a federal prohibition on states' ability to legalize sports betting, but otherwise yes.

Except it's not the same gambling in both cases, they have qualitative differences beyond simply where they're happening. My unhinged neighbor who'd threaten a journalist probably doesn't have an invite to the Underground Gambling Den.
Even if he did, when a court case happens there's no presumption of normalcy. He can't say: "Pshaw, everybody legally gambles on all sorts of things there, the fact that I bet big on the journalist not having his fingers broken is just coincidence."
The immediate illegality of the gambling is also a check on corruption, since it's already disqualifying for Judge Stickyfingers McBriberson to be on the platform, let alone "betting" on the outcome of cases he presides over.

I don't see why we should assume that. Making something annoying to engage in dramatically reduces the amount of people who engage in it. If illegal gambling rings operate, you'd have to 'know a guy' and the gambling ring would -- by definition -- have limited scope.
It's like saying "legalize fent" to protect people who use fentanyl. Like, yea, the problem isn't the addicts, it's that if you can sell the drug in a store, you're going to get 1000x the number of addicts. We need frictional barriers to prevent people from becoming addicted in the first place.
The previous system was fine. We had a couple highly regulated areas where you could travel to (Las Vegas, Reno, a few Indian casinos) for people who were obsessed with gambling. That meant the rest of us were mostly left alone, and not tempted to engage in the vice.
