Twice over. It needs a liquid public security a lender will lend against cheaply, which private shares in an Ontario CCPC are not — a lender will look at your personal covenant and your real property, not your cap table. And on this week's evidence it is overstated even for the people it is supposedly about: they sold, at size, including the twenty-year-old zero-basis stock that the theory says should never be sold. Treat the idea as a real technique used narrowly, not as the organising principle of how wealth is kept.
