> He is "correct" in a way. Perhaps if the age difference is very small, but see hereunder. However, there is a good reason why a minor isn't able to sign a (legal) contract. Because they're not an adult. The brains stop growing at around age 25. The body at around age 20 / mid 20 (depends on gender and differs per person). So at age 18, teenagers are still growing up. A teenager is unable to consent to an older adult because the relation isn't equal. The adult (presumably) is grown up. It has the huge potential to create a power vacuum. Which is why we need to be very careful to protect our minors. Which is why if the age difference is minor, its often tolerated even if it isn't exactly legal. Alas, the law is not perfect, but the lawmakers did did try their best to make the law as far as possible for all parties involved.
