They're rich.
The Amish are extremely business savvy, shrewd negotiators, and have no issues being active members in the economy. They also own vast tracts of very valuable land (especially in Lancaster, PA). Combine that with being frugal and austere, and it's a recipe for wealth.
For childcare, their community focus let's them share the burden amongst the larger group. Additionally, children are not nearly as coddled and are expected to contribute to the family's work, and help co-parent their siblings.
Compare this to the average nuclear family: underpaid, barely any savings, most likely rents, and lucky if they have even one family member nearby that can share the childcare burden.
Since childcare is mentioned, I would be remiss if I did not point out that the Amish have a disproportionate rate of child sex abuse. Offenders often get off because the Amish community pressures victims not to testify. Victims are sent to re-education centers. It is pretty gross what goes on in plain (pardon the pun) sight. But they bring in tourist dollars. Most Amish are lovely of course, but their lifestyle has a very dark side.
There's no guarantee that buying a house will leave you richer than if you'd rented during the same time. Check out this calculator to explore your personal situation more closely, and examine the assumptions you make about growing wealth.
I know from personal experience, owning my first home, that I almost certainly would've been better off renting over that time period and investing the down payment and higher monthly payments than I ended up with having that house and equity. Sometimes you get lucky - and house prices go up and you sell at the right time (assuming you switch back to rent OR manage to then buy in a market where prices are lower than average.)

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.
