There's no need to be against to those people that are looking to see the new generation not to get addicted in gambling. Even us, we're also into gambling and we don't want teens to get addicted on it.
If that's the way they are seeing it, it's not the best solution but it's a way to reduce the number of teens getting addicted. IMO, the best is still to educate the parents so that they'd pass it on to their children to not to engage in gambling.
The time will come for these teenagers that they will realize that life isn't just all about them gambling all day long or getting some money from their parent's pockets.
While those that have side hustles, they can do whatever they want with their money. Yes, there are teenagers nowadays with side hustles but still that doesn't give them a pass to gamble.
