I'm guessing (hoping) there is a miscommunication here, since you literally restated my original point as correct, and are implying I am stating what the GP I first replied to said when I was arguing against him.
The whole point is: if you want a nanny state, please go elsewhere. That's not the kind of country America was ever intended to be, and most of us don't want it.
So if you do agree with the original poster and think I am wrong, you agree with him that a 30-40 year old should have the right to have sex with a 10 or younger year old... and that is "America"
Really?
The rest of your post basically boils down to, using age to determine if a person is ready to handle sex is bad (you argued against me saying it's not bad twice now)
Using age, yes there are areas where it's hard to tell, but there are MORE areas where it is not.
Let's use some numbers.
A 10 year old girl, or younger, is very clearly going to look "young"
A 30 year old girl, or older, is very clearly going to look "adult"
In those cases, it is very simple to determine age and if it's a good idea to have sex with them.
No, that doesn't address people between 15-20 who could look either way, but it addresses some.
It certainly addresses more than zero, as the original poster wants, which I repeatedly objected to.
You are arguing a person MUST get a certificate from the government that deems them an adult, and this certificate can not be based on age.
(That is the exact argument the original poster made, and I argued against to him and to you)
Again, I quote

Your objections to an "adult test" are exactly the same objections many people have to a "firearms proficiency test" in order to get a concealed weapons permit. Who decides what is competent or proficient? The State?
That isn't my objection. I argued against that very thing three times now against two people.
I pointed out the state is clearly NOT qualified to determine sexual maturity, and that is exactly why they do not do so and set an arbitrary line of "Xth birthday"
Only the original poster (and now you) are saying I am wrong, the state IS qualified and MUST issue certificates on a per-individual basis because that is the only method to be factually correct.
So to answer your question, who decides who/what is competent or proficient?
You are, since I claimed the state can't possibly do this, which is why they use the current system of age that clearly doesn't reflect if a person is able to handle adult situations like sex or not.
