"Guess what, LIFE is a gamble, with every decision you make. Nothing is guaranteed, everything is chance. Driving to work every day is a gamble that the risk of the travel will be worth the pay off."
Sure, but do you expect that you will be killed by a raging driver on a regular basis because there is no law against rage driving or traffic regulation at all? Or do you actually believe that collective drivers in a free society will spontaneously organize themselves to some unwritten rule in the absence because ..?
"It's also shitty parenting if you keep giving your kids money to blow on loot boxes. Teach them budgeting, you get what you get and that's it."
Who's going to protect the rest of us from actual shitty parents' kids when they grow up? Shitty parenting also begets thieves, murderers, homeless, and general undesirables. Not that all of them turn out that way, of course, but maybe for the sole interest of the minors, regardless of parents, that we should put in place a means to protect them (and us)?
All of your arguments devolve to: there's always going to be X, so laws against X is a form of regulation and therefore is ineffective and should be abolished or not passed in the first place.
Meanwhile in the real world, we pass regulations or laws that we reasonably believe will curtail majority of the problems and not toss the responsibilities to bad parenting or whatever Libertarian beliefs you hold dear to.
It's not all or nothing deal.
