This will only mean the most vulnerable (who need the most support) will be unsupported. You're creating an underclass.
You'd be surprised
The traditional "license" to have children used to be marriage, and children born without such a license were called illegitimate - i.e. outside the law. It was an unjust system that hurt a lot of innocent children, and we've moved away from it for a reason.
If the current system (where marriage and procreation are notionally separate) were found to hurt a lot of innocent children, would we call our system unjust and abandon it?
I suspect not. The current culture around marriage and parenting didn't evolve from pragmatism as much as (various takes on) ethics, morality, and self-determinism.
That alone will prevent many unplanned and unwanted babies in a population without any force, political, eugenics or racist overtones.
I don't know the long term effects of these implants so it's a tentative idea.
Yes, Nazi Germany did some shitty stuff for ideological reasons and tarnished the "eugenics" label, but it doesn't invalidate the basic idea of influencing human reproduction and/or selecting for preferred traits and/or direct DNA interventions.
In practice, eugenics seems to move from "some genetic makeups are more fit for the current environment than others, and we should strive for those in future generations" to "some genetic makeups are better than others, and we should strive for those", to "some people are better than others, and we should strive for those", to "some people are better than others, and we should force there to not be so many of the others". There doesn't seem to be any clear point at which you can say, "No, you've gone too far", and explain to the true believer why the step they took is too far. They'll just tell you that it's logically implied by the steps that you are in agreement with.
And if you disagree with this, show me historical examples of eugenics movements that stopped at reasonable places. (I probably need to qualify that with "eugenics movements that had some influence", because if you don't have enough influence to get people to accept step 1, you don't move on to step 2. And that may be begging the question on my part, because Nazi Germany may be the only historical example where the ideas got taken seriously and actually influenced much of anything.)
Unrelated comment: Another danger of eugenics is exposed by my wording of the starting point: "some genetic makeups are more fit for the current environment than others..." That's clearly true. But the current environment is not necessarily the one that future generations will face; leaving them some genetic diversity (even if it creates some disadvantages) may be a net win. Remember sickle cell anemia.
Because it doesn't. I will assert that even though I'm not a Marxist True Believer.
> After seeing too many examples of it working out badly and none at all of it working well, we regard the idea as invalid.
And that's just plain stupidity, which is exactly what I'm complaining about. It's "someone tried that before some time ago and it didn't work, therefore let's label this stupid and throw it away" kind of attitude. The real reason we're ignoring the entire idea is because communist propaganda has lost and US propaganda has won, and it has little to do with actual merits of the idea itself.
You could utter similar dismissals for fire before we mastered it, or for gasoline before we created ICEs, or for powered flight before Wright brothers. What I was asking for is an actual discussion of the idea - pointing out where the idea is wrong, and talking about how can we modify it to avoid its problems while reaping the rewards.
Which fortunately you did in the rest of your comment, so forgive me for the text above, but I really really disagree with the sentiment of your first paragraph.

I don't think we had many of such examples - the only ones we label "eugenics" happened within the last 100 years, and involved powerful people with ideology doing stupid and harmful things because doing things because of an ideology is generally stupid and harmful.

Yeah, that's a strong point I'm going to agree 100% with. Too strong adaptation to current environment means you'll be really out of luck when the environment changes.
You don't want to do that after one failed attempt. You probably don't want to do so after two or three. But after enough attempts, you probably have a basis for saying that, no matter how good the theory sounds, it won't work in practice next time either. And if each time it fails produces large amounts of human suffering, there comes a time to quit trying the same stuff that has worked out badly over and over.
Heritably curing the cystic fibrosis gene with an injection? That's eugenics.
As a sibling comment notes, eugenics is conventionally understood to be gene selection via people selection, i.e. differential all-or-nothing biological reproduction of whole humans. And it was that sense of the idea I was critiquing.
And it is in that sense of the word that people shooting from the hip with talk of "licensing" the basic human right to reproduce are engaging in shocking historical naivety -- or worse, with facepalm-worthy apologetics like those corners of the commentariat that defend misogyny, slavery and other social aberrations that have rightfully been interred to the dustbin of history.
Because I'm pretty sure that would satisfy 90% of the historical proponents of eugenics, even if you refuse to call it such.
One is unfocused and hard to target genetic manipulation via reproduction incentives and force, the other is a choice for very targeted and obvious things.
Up until the 1990s in Spain, many thousands of children were systematically stolen from political activists and others with the wrong politics or wrong lifestyle. Parents were told that their newborn had died. http://www.bbc.co.uk/news/magazine-15335899
