This is a ridiculously exaggeration of what's going to happen, if the law even gets passed at all.
It'll likely only cause retailers to be more strict on their employees. If a store stops selling a certain rating of game, then customers are going to go somewhere else, giving more incentive for rivals stores to continue selling those games. Retailers may even launch mystery shopper campaigns on their own stores, to enforce their rules, and stress the illegality of selling to minors.
Nothing else will change, except from kids being forced to get their parents to buy a lot more of their games.
