No, I'm simply not making the mistake of taking my own conclusions and assuming the author is making THAT point. Whether you are right or not, it's not the authors point with that line. NIMBY was the point.
As for whether you are right, you might think this personal mobility v capital mobility is a clever sounding point. It's dumb. The idea that one simple idea has led to concentrations of wealth is absurd. It's useful in life to actually think things through, rather than parrot phrases you've heard in econ 101. You are literally clueless.
