Although you replied that you did not read the article first, I think you still do make a valid point. Here is an excerpt from the article:
> Of course, some lucky people already know exactly what they’re retiring to, answers firmly in hand.

The _second_ example here already calls out that it's going to be common to do parenting 14 hours a day if people retire early. For someone who has kids, it's pretty unlikely to be able to roll with life and see what comes up. It just isn't possible, with or without a job, being financially independent or not. And whether we like it or not, a large percentage of the population above 40 do have kids.
This is purely my opinion, but I'm actually not sure that, for a child past 2 years old or so, if it's a good idea for a parent to be with their child 24/7. I think there's a lot of value in learning social interactions with other children in a daycare or preschool. I did this exact thing for 3 years and am transitioning the child to preschool at 3 years old, and it has been difficult.
On top of it all, let's say your kids are school age, somewhere between 3 to 16. Let's say they go to school during the day, and you have free time during the day. There is another discussion to be had about your kids' mentality if they grow up with parents who don't need to work. Sure, maybe in the near future, in this next generation, we'll enter a society where work is unnecessary and everyone lives off of UBI, and maybe the discussion is moot. But assuming that won't be the case, would you want your children to grow up with the impression that when they grow up into adults there's no need to do any productive work, or have parents as role models who contribute meaningfully to society?
Maybe I haven't thought it through, maybe I'm just not smart enough. I'm at a point in life where I could feasibly "lean FIRE" if I really want to, but for the sake of my child I'd rather continue to work. Which then leads to answering this post, my FI and retirement almost isn't about me, it's about my child/children. Or maybe that just means I'm that guy who said "I'm going to do a lot of parenting" then.
