So, why isn't this a thing yet?

There's no law, because pedophilia isn't illegal. It's a psychological ailment. Child pornography and child molestation are illegal, but they are crimes generally committed by pedophiles.
Pedophilia, again, is the attraction to/having sexual urges towards children. It doesn't matter what visual form. In fact, loli and shota doujin gives pedophiles an outlet to express their sickness. If they didn't have those, they would most likely be viewing either 3D renders or pictures of real children.
The fact of the matter, as Sam has pointed out several times now, is that creating a race that is quite obviously modeled after children will only encourage pedophilic behavior. Especially if they're able to sexualize said race. And no, just claiming that "the members of this race are adults and X number of years old, yet they look like children" is not acceptable. That would be the exact same as showing a picture of child pornography and saying, "Let's just pretend she's 18".

there are laws in place that are in reference to having child porn, but said laws exclude animated(3d is cutting close)/print, as it has no bearing on reality. it hasnt stopped people from trying to charge others of having child porn, but yea. its there.having a child like race does not automaticly mean it will promote the behavior you say it will, as there is no direct proof of this.

also, there is no "lets pretend she/he is 18", at least legally. if i made an original doujin and it had a a chr that looked underaged, but is stated to be over a certain age(also known as word of god(as the creator of said thing, i am its god, a bit silly)) you, as a reader or critic dont get to nitpic and ignore what has been decided.
as for the outlet part, are you going to include everything that is illegal/sick? this would include tankobons with people getting killed,zoophilia,corophilia, body modification, brain draining, ryona, cbt, and other things like them? oh wait, none of those are illegal in drawn form because they have no effect on living people. for something to be illegal it has to have some kind of impact in reality.
