I think, given his familial situation, Elon's argument is basically this, saying the other quiet parts out loud:

" I feel compelled to shame others into having children to take care of me in my old age because I realize I cannot count on my own children to do so since I've been such a monumental shithead to them that two of them will not even speak to me. So I'm selfishly going to need all of y'alls to have more children for me to continue being a monumental and now also colossal shithead to throughout the remainder of my lifespan. We all know that since I bought Twitter, I've elevated to Shithead Extreme. I'm El Jeffe Shithead. Just call me La Testa di Merda and send me your kids. My ass will soon need wiping. Don't be selfish!"

If we're just saying the quiet part out loud.

His kids are gonna get to tap out so you need to procreate him up some replacement caretakers. Your kids are gonna be corporate feudal serfs.

There is so much projection in his comments.
