Not to be obtuse, but for what definition of putting money, and what definition of gambling? I think it's reasonable to distinguish between, say, holding Berkshire Hathaway and day trading. And I'm not sure that you can lump the two together into a definition of gambling that doesn't end up being too broad to be useful.
The effects of gambling aren’t good. Been to a casino? They’re sad places. It should be illegal the same way heroin and fentanyl is. Lots of ppl use opiates, and most don’t end up ruining their lives and that of their families. But there’s quite a few who do, and those folks end up on the street, families break up, and you get a lot of petty crime, squalor, and health problems that your community ends up paying for one way or another. All to make some asshole getting paid from addicting people rich.
