People with the type of net worth to make the considerations identified in the article choose home ownership (and typically multiple homes) 9.5/10 times.  I know this for a fact from the multi-hundred person sample set I associate with, and my own experience.  People in this category have paper assets, real estate, business interests and cash and move between them for many different reasons (including the downsizing example and very specific visiting-executive scenario from this article).

The picture is indeed very incomplete.  People in this bracket do not have simple scenarios that can be described on a napkin.  For example, 1. typical people in this situation would likely give up 1-2% of investment returns to an adviser, right off the top.  2. if you are producing $250K in eligible dividend income you are paying above the capital gains rate eating into your  perceived benefits.  There are several other similar issues to consider.
