I must disagree with your assertion that seeking IVF and other illicit technologies are on par with cancer therapy or the like. That is not even close to the truth. We certainly have a right to correct a pathologic condition, within reason, but we do not have any right to correct it by using immoral means. Just because I may be sick does not mean I have recourse to every possible way to correct it if it means violating the moral law.
Also, people in lab coats, like other folks, have a free will. God will not violate anyone's free will. So, even if they want to commit an evil, God will not stop them. If they want to thwart God's will and plan for human reproduction, He will not stop them. In fact, like all sin, at some point God will turn them over completely to their sin as punishment. They will seek even greater ways to thwart God's will, and still say it is not sinful.
Thank you for your kind thoughts.
I agree that we do not have the right to correct any medical condition -- cancer or infertility -- by immoral means. The question here is whether IVF is immoral. In my view, creating then abandoning embryos would be immoral -- so we agree on that. I am not convinced, though, that IVF itself is immoral.
