"the policy would have worked" - in what sense? Are you genuinely arguing that eugenicists would have objectively and accurately determined which genes led to strongest/most intelligent/most productive humans and only allowed people with those genes to reproduce, and successfully ensured "defective" genes were eliminated from the homo sapiens gene pool? Even if somehow they had achieved that, the thought of living in a society where a human life is only considered valuable if it fits some predefined criteria is frankly far too high a cost to pay. (Interestingly I was watching Man in the High Castle last night, the episode that "celebrates" the choice of one of the characters to have himself be euthanised because of an incurable medical condition. It was an odd experience because superficially it came across as a very powerful and moving scene, despite the horrid underlying creepiness of it. But it didn't seem hard to believe that people could genuinely be swayed into thinking that it was a "noble" thing to have your life terminated just because of a particular genetic condition. I suppose at least it's a more justifiable stance than believing that anyone not of a particular race was undeserving of a fulfilling life, though clearly many eugenicists believed exactly that too).
