It should be pointed out that it’s possible to agree with most or all of your predictions, while disagreeing with their valence, or in other words, to say: “Yes, all these things indeed are likely to happen—and that’s a good thing!”
I do not endorse this view myself, but it’s important to realize that many people do, and such people would respond to your points in ways somewhat like the following:
Where are we to get our people from, if not from our own citizenry? …
“Our society has no greater value than anyone else’s, and replacing our citizenry and our culture with other people is not inherently problematic in any way.”
We know the recipe for killing population growth, and we’ve deployed it successfully in Africa (and by accident, here too): education for girls followed by employment (and you don’t even need birth control to see the dramatic effects).
Playing the devil’s advocate:

“This is not only not a problem, it is a positive good; what you describe is indeed the recipe for the liberation and empowerment of women.”
… and so on.
I bring this up only to remind everyone in this conversation to keep a very firm grasp on the distinction between ‘is’ and ‘ought’.
