Highways (and resulting sprawl) aren't the result of free market economics -- they are a policy decision.

I currently live in Ann Arbor, MI (the 244th largest city in the US) without a car. If they built a Trader Joes downtown I would have 0 issues being car free. The city has built a number of fully protected bike lanes downtown that I hope get expanded further into the greater community, and seems to be doing a good job of making the downtown denser as well. It certainly can be done.
