I may be misinterpreting, but I think that what the quoted post is talking about is probably independent from the kind of development you’ve mentioned. For instance, while the person who never moved from their hometown might’ve been able to hit societal goalposts earlier on, they may never have had the opportunity to explore, experiment, and figure themselves and what they want to do out (as opposed to the identity they’d picked up via osmosis from family). Speaking personally, in retrospect I was certainly underdeveloped in that way until my late 20s and early 30s, even though I couldn’t perceive that at the time. The requisite independence/autonomy and experience just wasn’t there until several years later. Had I locked myself into my situation with a marriage and children at that age I think it’s quite likely I would’ve come to regret it in the years following, increasing risk of outcomes such as divorce.
