So it doesn't matter that a very small percentage of the world's population believes life begins at conception, it's still unethical? Or is everything unethical that anyone thinks is unethical across the board, regardless of the other factors? Since some vegans believe eating honey is unethical, does that mean it's unethical for everybody, or would it only be unethical if it was illegal?
In autocracies where all newly married couples were legally compelled to allow the local lord to rape the bride before they consummated the marriage, avoiding that would be unethical?
Were the sit-in protest of the American civil rights era unethical? They were illegal.
Was it unethical to hide people from the Nazis when they were search for people to exterminate? It was against the law.
Was apartheid ethical? It was the law.
Was slavery ethical? It was the law.
Were the jim crow laws ethical?
I have to say, I just fundamentally don't understand your faith in the infallibility of humanity's leaders and governing structures. Do I think it's generally a good idea to follow the law? Of course. But there are so very many laws that are clearly unethical. I think your conflating legal correctness with mores with core foundational ethics is rather strange.
