I understand that, but this case will be used by NAMBLA, the ACLU, et al to challenge state laws against child molestation, and, depending on the state they sue in, they may get an appeals court to side with them (the 9th circuit is probably salivating in anticipation).
As it is in America today, SCOTUS would allow laws against molestation, but give it 20 years of molestors bullying there way into the mainstream (just like the homosexuals started to do in the 1970s) and you may have a different verdict.
