This is an all-too-valid point, especially for "young people" who really are not ready to be independent adults.
If Chris graduates from high school, gets a 3/4-time job working at Pete's Pizza Parlor, rents a little apartment to live in, and starts taking old-fashioned correspondence courses from Snail Mail University - then there is near-zero social or legal expectation that Chris' landlord, or his boss Pete, or SMU will provide Chris with much anything in the way of baby-sitting, peer advisors, medical coverage, mental health services, recreational facilities, parallel justice systems, etc., etc.
Vs. if Chris' twin sibling Pat graduates from high school and goes to Big State University...and then has a major mental health crisis? There might be an ultra-luxury resort, somewhere on this planet, which actually provides the level of mental health service which seems to be expected of any university. Might.
