He or she meant by population I would assume. Approximately 5 vs. 10 million.
Exactly. I would assume that the higher the population, the more buildings present. Just because you have a lot of land doesn't mean you have a lot of buildings.
I don't understand why this is needed. Here in Finland the government just gave this info out for free to anyone (CC 4.0). They have all the information anyway because they have need for it due to planning/building permits, defense, etc. The data is very accurate (for example I can zoom into my parents cottage and see the out house on it). Later on they used laser scanning from planes to scan the whole country for ve…

Take the size and complexity and federation into account... In Switzerland we have map.geo.admin.ch with a highly accurate representation of the levels and buildings. I love it

People like to say that, but in practice it's not true and hasn't been for over a century.
People like to say that, but in practice it's not true and hasn't been for over a century. It depends on the topic. When it comes to things like interstate commerce, you are correct -- the states don't each have treaties with each other. But when it comes to other things, like education, that's very much a local function. The feds set minimum best practices (enforced by the threat of removing funding), but it's up to…
I think the US shows itself to be pretty homogeneous, with some differences between the rural, suburban, and urban areas, but not much.
If anyone is interested in that type of data, our startup ( https://tensorflight.com ) extracts information like footprints and 10 other property factors for insurance (including bing imagery). More info: https://tensorflight.com/catalogue#Objects-supported-by-Tens... .

The USA is about 30x Finland's size by landarea and building data is primarily stored at the county or equivalent level of government (3000 of those). Imagine munging data from 3000 different counties, each with their own standards and systems of recording.
It should be trivial. It should be standardized. It is absolutely bizarre that we need to rely upon commercial companies to map things like streets and buildings when this is very accurately tracked by government. In an ideal world OSM data grids could be delegated to the appropriate governments, where it could have perfect precision with changes, street closures, one ways, redirects, etc.
Additionally, there is enough problems getting the global OSM community to come up with one tagging scheme. If every country made their own stuff, it would not be one map.

The United States is comprised of literally thousands of sovereign, independent governments. There are even independent limits on what rules these governments can impose upon each other. It is not a "subordinate" type of situation. That's why the size argument comes into play so often. It's not really a landmass or even population argument as much as is it a complexity argument.

We just had a Supreme Court ruling affirming states’ anti-commandeering rights [1].

No thank you. New York City doesn’t need a federal bureaucracy to be checked into every time a building goes up or a pipeline gets laid. And the level of detail which is necessary for New York would be overkill for rural counties; they have better things to spend their tax dollars on.
