This is factually false :) and if you’re really worried, there are many options available to you to preserve what you will need or consider adoption - there are so many humans being born without a family after all.
I agree with you on a factual basis, but you understand that a large amount of people have a deep emotional instinct to not be ok with those options, right?
Most people I know realize they should have had kids sooner once they have them. Adoption is also not that easy, there are plenty of cases where adoption causes kidnapping.
