> I don't see any evidence that the "collective harm" you mention from the article is anything other than individuals making bad financial decisions.
Legalized gambling establishments do very little besides extract money from visitors and project negative externalities into their surroundings.
> I believe that I, as a responsible adult, should be allowed to gamble for entertainment if I want to, and my right to do that shouldn't be taken away because a small minority of the population has low impulse control.
You can believe that, and be correct in theory. In practice, the "small minority" doesn't appear to be small enough under the current regulatory regime.
It's no different than the regulation of controlled substances and other vices. Or do you have an issue with that as well, and feel you should have the right to consume as much heroin as you want?
I'm pretty liberal when it comes to drugs. I think it's a case by case basis, but I do believe that heroin and most other drugs should be legal and regulated. As long as there's demand, prohibition just leads to black markets, funnels money to cartels, and consumers ultimately get a less reliable and more dangerous product.
