Do you have any answer to the OP's preference for raising children in the space and privacy of a single family home?

Yes, the Netherlands have a large amount of single family homes without the need for American-style suburbs. Over 56% of all Dutch citizens own at least one house, 69% of all residential buildings are owned by the people living in them. Those houses are mostly not oversized like American houses and have less land attached to them. For comparison, the home ownership rate for the US is about 65.3%.

Everything points to the American way of doing housing and infrastructure is wrong and could be done cheaper and easier if American city planners were to look at other parts of the world.

You don't need a massive backyard for that.
