Ah ok, so you are fine with taking your child to Las Vegas and sitting them in front of the slot machine with a handful of quarters? Maybe just give them a small heroin injection too, there's a chance they wont get addicted.
Also, giving your children unfettered access to the internet is not the same thing as giving them money for a slot machine. They don't have money unless you give it to them. It's not difficult to prevent them from having unlimited access to your credit cards.
Children will grow up into adults that have access to all this stuff anyway. Better to teach and manage excess early then restrict.
So clearly it's comparable to heroin and slot machines at Vegas then, if we don't know the impact. Just gotta get a couple more years in to know for sure whether we can compare it to opiates :)
