I'm not sure this rather dated precept is compatible with the exigencies of 21st century economics, and the flexibility, mobility and long hours demanded.
For one thing, houses are cash sinks. It doesn't make sense for highly paid professionals to spend enormous amounts of time or money reshingling roofs, painting, mowing lawns, treating weeds, trimming hedges, repairing plumbing, etc. The deep specialisation and constant attention that the professional economy asks are orthogonal to all those things. It's prudent to upload those demands to the cloud (aka your landlord, at scale) so to speak.
I know far more urban professionals that were hindered by the ballast of owning real estate than those empowered by this "most basic form of security". Here in the sprawling metro Atlanta area, taking another job will very likely take you to a wholly different part of this vast agglomeration and doom you to a punishing commute unless you sell your house and relocate. The uncertainty, transaction costs and other friction kept a number of people I know in dead-end jobs until they were finally laid off.
As a personal anecdote, I bought a condo in May 2007. I was drinking the very same Kool-Aid about basic form of security and whatnot. I finally let my home go to foreclosure in summer 2015. I financed at $160K, and in summer 2015 it appraised at $85K. I still owed $140K. One of the lenders sued me for a $29K deficiency and got a judgment, and I'll be paying them $250/mo for the next six years. Some security. I grant that my effort at partaking of the most basic form of security a human needs was exceptionally disastrous, but I think the housing crash educated a lot of people about just how much security it really offers. A senseless push to ownership for ownership's sake threatens to discard those valuable lessons.
The real argument for owning vs. renting is the mortgage interest deduction, and that's an artifice of government tax policy that hugely distorts the market and the incentives.
