Ownership has its privileges, and there's a cost to entry.
I have a music store near me, and I can rent a specific PA system for the weekend from them for $135, or I can buy it outright for $549.
Well, $549 is a lot to pay if I only need it for a weekend, and it may be foolish to ruin my event over $135. So there are times when renting is more cost-effective than owning.
However. Why rent in the same place for five, seven, ten years or longer, paying off the landlord's mortgage, when you could have been paying off your own mortgage?
While I have a personal "Ownership Mentality," and want an unencumbered deed to my own piece of dirt, that is not for everyone, and I should not be selling that lifestyle choice or creating urgency to own.
I believe strongly that is a matter of ethical behavior. "Selling Ownership" steps too close to or even directly into self-serving behavior, rather than providing fiduciary service.
