Freedom is a birthright, not a reward that must be earned.
It is my sincere belief that people should be judged and treated solely on their individual merits, not their age. Adolescence is the invention of industrialized society and is used as an excuse to deprive young people ages 14 to 18 of the freedoms they would have already been granted in a more natural state.
Childhood should end at the first sign of adolescence and adult status should be immediately granted. Anything else is a violation of a person's natural rights and a gross disrespect.
In my libertarian America, the age of consent would be lowered from 18 to 14, the usual age of the onset of biological adulthood. Young people at this age would have the right to stay out all night, move out on their own, work full time, sign binding contracts, smoke, drink, drive, own a firearm, watch whatever movies and play whatever video games they pleased.
