As you said:
> I'll get to my deathbed and regret not having a family of my own to enjoy time with.
Is that not selfish? Making humans to fill your time? Humans who are in no way guaranteed to want to spend time with you between adulthood and your death [1] [2]? I'm not going to argue against it in this thread, but let's call a spade a spade. I can respect "I am selfish and am making this choice, consequences be damned," but lets not dress up having kids as a noble cause when there are 8 billion people on the planet.
Not directed at you, but a phrase I use often with people considering kids is "Do you need kids? Or therapy?" Enumerate why you are making this decision, and provide evidence supporting this decision. The worst I hear, far too often, is "I'm having a kid so someone will love me forever." Big oof, let me tell you how that goes. I'm arguing for more thought and intention into the default choice, because the outcome is mostly permanent and a one way door. Is it worse to regret not having kids? Or regret having had them?
~40% of annual pregnancies, in both the US and internationally, are unintentional (per the Guttmacher Institute and the UN, respectively), so I think folks who really want to have kids aren't going to be material as long as those folks who don't want them have their reproductive freedoms affirmed.
