Gambling might be ripping though the US, maybe. But it's far from unfettered.

You might like to read about what economists call 'Normal Goods': https://en.wikipedia.org/wiki/Normal_good
> In economics, a normal good is a type of a good for which consumers increase their demand due to an increase in income, unlike inferior goods, for which the opposite is observed. When there is an increase in a person's income, for example due to a wage rise, a good for which the demand rises due to the wage increase, is referred as a normal good. Conversely, the demand for normal goods declines when the income decreases, for example due to a wage decrease or layoffs.
Health and safety are normal goods. As people get richer, they demand more of them.
Look what it took to wrangle the cigarette industry. Look how unfettered gambling is ripping through the USA.

At minimum we have as much evidence that "the market" is capable of being as bad as "bad regulation."
