> I agree that a stable family is the ideal but I fail to see how spending your money on sex dolls is worse than getting divorced in your late 20s or early 30s and getting stuck paying for kids for a decade or more.
No, the point of a stable family is the relationships. Kids may be one of those relationships.
The point of reproduction is kids, and they can happen without a stable family as well... Quite often in fact. And they can be raised in different arrangements too, like wards of state and in kibbutzim, which is implemented right are not destructive. Or even by single parents (but that one is hard) or by surrogates who have a stable family.
But the point of the stable family IS the kids.
