And yet plenty drugs and medicine are controlled substances because they’d be so easy to abuse or hurt yourself with. We could just assign the same to ingame gambling, no? Since that’s also on an individual basis, handle it the same all around?
So to buy a lootbox:
Go to a doctor.
Doctor prescribes you a daily dosage of say, 1 lootbox.
Each day you can go to the pharmacy and pick up a pack of 1 lootbox code, you can have at maximum a store of 4 of them at home then pharmacies stop giving you more so you cannot stockpile. (going by the pills a friend of mine gets prescribed here)
