Density is not an argument (Score 2, Insightful)

Ok, the population density in Sweden, Japan, and South Korea, is more than the population density in USA taken as a whole. But we have many cities here, with a sufficiently high population density, i.e. at comparable levels to the urban areas in those countries, considering this, how can the density argument hold?

Even in those countries, it must not be the case that every nook and cranny of them is getting broadband at 100Mbps, probably many of the rural areas are still working on the low speed ones. Considering that our cities have a very high population density, what is stopping us from getting the 100Mbps broadband?
