Zoning for who? America has no issue with single family zoning.

I’m assuming you’re speaking about middle and high density zoning. Since the issues you're describing are extremely common for those zoning projects.

If you're the property owner it should be easy for you to build whatever level of residential density you want and think the market will make profitable. Why is it illegal for me to build townhouses on my land?

I'm in an area where it takes, on average, 1.8 acres per single family home. The next town over would put 18 single family homes in that same space. Zoning is restrictive even for single-family homes.

I don't think that's a particularly representative example. Zoning is determined locally in the U.S., and taking the most extreme locality doesn't really shed light on what's going on in the country as a whole, and isn't a useful avenue to approach this problem. Try instead to work with averages and representative localities. The U.S., like any area, has urban, suburban, and rural areas, with a continuous gradient in between. No point in discussing rural or near-rural areas when complaining about zoning, since the real issue is that people in urban areas need access to jobs. People living on the horse farms or rural ranches are not the problem here, and liberalizing zoning in Asheville isn't going to make housing more affordable in Austin or San Francisco, which is where the pain of restrictive zoning is felt.

Zoning density is based partially on supporting infrastructure. If low density suddenly becomes higher density, will the roads be able to handle the additional vehicles/trips? Probably not, so who will cover costs to improve the roads so individuals can build multiple townhomes in their property?

This is precisely what impact fees are for when applying for building permits.

Isn't the entire concept of externalities in economics that things aren't that simple? Presumably you agree that your neighbor shouldn't be able to build a sewage treatment plant next to your house.

From what I can tell most economists will actively go out of their way to ignore externalities. For some externalities there are even market based methods for getting rid of them yet curiously almost no economist is interested in these types of institutions.

Sewage treatment plants are not residential construction.

Move to Texas and you can literally do this. There is no zoning. Go ahead and build those townhouses on your land. Your next door neighbors might build a strip club or pesticide manufacturing plant, though.

Even if you luck out with your current neighbors, the addional risk will lead to worse terms for you if you need investors to finance the project.
