The author of this article unwittingly makes the argument he was trying to oppose, which is that money drives your choice of location. He acknowledges that his startup was 100% bootstrapped and profitable. In those happy circumstances it doesn't really matter where you are located, unless taking venture capital would help you grow faster (if fast growth is your goal).
