Why does 'the law' assume that age 18/21 is the optimal age for making decisions?
But don't you think that some people mature faster than others and are capable of making important decisions before the age of 18/21?
That is possible, and some laws make exceptions for individuals who demonstrate maturity and responsibility at an earlier age. However, the law has to set a standard that applies to everyone, and it is believed that most individuals will be able to make informed decisions at around age 18/21.
