Also, if you go to the Strong Towns[1] website that Charles Marohn helped start and read the Mission Statement and their Quantification of a Strong Town, nowhere does it talk about population density or converting suburbs/towns into cities.

You mean like these?

He absolutely is talking about density. The tax bases of low density suburbs, compared to the maintenance costs that they require, are inherently disparate.

The costs of building greenfield infrastructure is low...low enough that developers willingly pay the infrastructure development fees in exchange for the right to build. But the taxes used to maintain the infrastructure do not cover the costs, and by that time the developer is off the hook. So they bring in new developers, which bring with them new taxes and more deferred maintenance, which brings solvency in the short term and bigger problems in the long term. Suburban-density development is a ponzi scheme, inherently unsustainable, and it is a theme that he refers to extensively in his writing.

The first three articles you linked to refer to commercial space, not residential space. I'd argue that they don't support your argument since I believe we're talking about residential spaces. Moreover, densely packed commercial centers aren't unique to cities. However, I suppose we can talk about those articles as well. They all refer to one specific case, the building of a Taco John's. The argument against it isn't that it takes up too much space, it's that it provides less value (in terms of tax revenue and how much money is being funneled back into the town through jobs) to the town than another comparable area. However, it's not just about the density of businesses. If we were to imagine a X-story high-rise containing X different businesses was built in place of the Taco John's, would that necessarily be better than the Taco John's? Not necessarily. You would need to take into consideration many other factors: the extra strain on the utilities, the generated tax revenue, whether or not it fits in with the characteristics of the surrounding neighborhood.

As for the last article, that one does talk about residential housing. I will agree that the article does talk about urbanization as the natural progression of town maturation. However, note that the article talks about progressions/increments (i.e. going from a house to a duplex, from a duplex, to a row of houses, from a row of houses to an apartment building) and not skipping those progressions (going straight from a house to an apartment building). In fact, the article specifically outlines that the changes must be natural, be compatible with the neighborhood, and must fit in. Overall, Marohn's more concerned with adding value to properties than increasing population density. He even goes as far as to specifically address our topic of discussion. I quote:

"I am going to pause now before going on to the next step and reiterate something important. I know there are those of you reading this right now, sitting at the kitchen table of your nice single family home, saying, "There is no way on God's green earth that I'm going to allow a set of row houses across the street from me. Who does this Strong Towns guy think he is?" Fair point, and the reality is that most neighborhoods will not grow beyond the single family stage. That's okay too, at least as long as the public infrastructure and services stay scaled to that investment level." Emphasis mine.

He states that what's tantamount is responsible spending.

That's not a Ponzi scheme, it's just poor planning.
