Because the game is Rated M for Mature(I don't know the rating systems outside of the US but likely for the same age group), for the demographic of 18+. Legally they have to put an age barrier to prevent younger people from stumbling onto the mature content.
I know that there are a million arguments saying kids see more brutal stuff all the time, but this is a legal reason put into place by the ESRB.

As far as I knew the ESRB is not an entity that can enforce or create laws that bar kids from buying games. The stores are the ones that do this themselves.
They put the age gate in when the game got an M rating. Cause...you know apparently 12 years can't do math and just put in the wrong age. It's a minimum standard in order to meet a compliancy created by an idiot bureaucrat somewhere.
