Businesses buy and sell off each other and also create value. But sticking with the “if everyone did this” every one would run a one person business. Not efficient but would work. On the other hand if everyone is renting out houses, they can at most be renting out one (ignoring foe now second houses/holiday apts). Then everyone would be housed and paying each other in a circle. So, no, everyone doing what the post suggests can not work. All but the first house would be empty.

All good points. The only dissonance for me is that I would expect that to happen earlier in their career.

They should know enough about how it works to not waste the time of those who work by asking stupid questions. But maybe that is why he resorted to asking the internet instead.

Such a sparkly string must be good.
