It's not wrong to be poor. Poor, honest people can have beautiful human qualities and have wonderful families. I'm a little perplexed about your point here.
Who is to say that a woman who has had a child by IVF won't get married a couple of years later?
She might, and more power to her. She's already demonstrated that she doesn't think a man is necessary to a family, nor an act of love the fitting way to beget a child. This doesn't bode well for future marriage. And the fact that she thinks her wants are more important than her child's needs, doesn't bode well either. Still, she could change. People do.
And any single woman who has sex and then gets pregnant could be said to 'deliberately' conceive...there's always a chance of getting pregnant, but those people didn't plan it.
True. Among the many reasons why nonmarital sex is wrong, that's one of the biggies.
Also, some people have great conditions in their lives when the woman gets pregnant, but then they divorce a few years later, or their financial situation changes, anything could happen.
That's true, too. But there's a difference between a family being wounded by divorce or death, and a child being brought into existence deliberately fatherless. In the latter, something is being willed for the child (intentional, planned fatherlessness) which ---and the mother has no right to on purpose deprive the child of his right to a father.
A father is not an optional or redundant feature. Per analogy, a child could lose a hand in an accident, and still go on to have a good life; but nobody should deliberately maim a child by cutting off a hand.
