Ah the good old days, when 10 year olds had full time jobs in the 1800's UK factories and spent their wages on gin unless parents beat it out of them for their gin. So laws came, school until 14 in UK, later 16, same in usa etc. No liquor to kids under 21 or 18 as geography dictates. So the internet wants similar age rules for age 13 or other age adult stuff and it progresses to that end. We see nothing wrong with kids 'carded' at bars to make sure they are 18 or 21? If valid age rules are set, how do we enforce them? Are we just to allow fully unfettered access to anyone who can hit a key? Some kids are smarter at 13 than others at 21 - should we have a mental competence test? Should we apply that to voter rules in elections. Obviously young kids of 12 want to pass as 18 to enjoy the pr0n that 18 years olds access - do we lose by short circuiting maturation? Island cultures often schooled young boys/girls in sex by older opposite sex partners, which Columbus's sailors found delightful as they were inundated by nubile young women who gave sex for pins/needles/buttons - also VD was passed over in payment, both ways.
