It is absolutely impossible to enforce. The internet certainly makes it easier for kids, but such age barriers are only a minor inconvenience really. Officially 18+ video games and movies can also be only accessed by adults, yet in my school a 13 years old kid literally ran a black market for horror movies and games like Call of Duty. It won't be any different for porn even if the government goes as far with blocking as the CCP.
