That's just what it boils down to: Add kids to the mix and you'll have them change schools (and their entire social circle) every time you do a career change - to earn more, to do something more interesting, or because you're simply forced to.

For anyone but singles, co-located work seems anachronistic. Worked back in the day were only one person in the family had a job, and jobs were held for decades (not years) I suppose. Today it seems ludicrous to expect anyone to move for work.

Which naturally leads into either long commutes or remote work. Having built several remote-first companies, I'm gonna say it's not perfect, but it really works.
