Yeah, I seem to remember the full phrase is something like, “Advice for millionaires: if it floats, flies, or [fornicates], rent it.” Advice does not apply to billionaires, which is a category Mike Lynch may have snuck into depending on whose reporting you believe.
As distasteful as the last part of that advice it, I can see the sense of the rest of it. You need to have enough money that the inevitably high ongoing maintenance costs (and I guess depreciation) simply aren’t a concern, or even something you have to think about because you have people to take care of it for you.
