I think this is an insightful comment and I'm sorry to see it get downvoted.
I live in a large condo building. It has its pros and cons. It's great, in theory--750-1000 people pooling their expertise and funds to tackle infrastructure issues. Great recent example: we fixed a sewer lateral (the pipe that connects to the sewer under the building). Three of them, total cost 200k. Sounds a lot until you realize we spread it across ~350 units (600/unit), which is roughly 1/10th what a typical suburban homeowner would pay for the same thing.
The other side of the coin is that, in larger political structures, governance REALLY matters. You can end up with a relatively well-run condo like mine, or a large, wasteful organization that squanders obscene sums on pet projects and outright corruption.
Many people don't even know this, but SF has been under federal investigation for high-level corruption in the public works department for over a year [1]. The thrust of your comment is correct. Large cities attract large amounts of money, much of which gets wasted, or ends up lining pockets in hard, or even "soft" corruption, with jobs and contracts steered to friends (qualified or not) via patronage networks.
What I think you miss though, is that there's a middle ground. You don't have to be either extreme drive-everywhere suburbia, or a giant mega-city like Beijing or New York. My home town, Homewood, IL, is a nice, walkable city of about 20,000, with a nice downtown, plenty to do, and relatively honest (if not always saintly) government.
The mid-size towns and suburbs can do a lot more to encourage the kind of urbanism the author calls for. Getting explicit about cultivating nice, walkable downtowns is a start. Many, including Homewood, don't, because "development" and "jobs" are seen as unqualified goods, without thinking about the cost side of the equation (roads, plumbing, etc required to service this stuff).
I've written for Strong Towns. What they get most right is that (1) LAND is the scare resource in a town, and (2) cities should explicitly encourage uses that lead to the highest taxable value of that land. Big box retail isn't this. Denser housing and retail districts (I own one of these buildings), is. The numbers on this are simple and don't lie.
