Anything I can say is purely hypothetical. Because we have no left-libertarian societies to study. But I'd like to believe that people would make stuff for use by people. People need to move? Cool. What's a good strategy? Isn't necessarily cars and roads. We'd probably have better land use policy and mass transit to optimize for moving people around. Also, the engrained corporatist rhetoric is that every belief to the left of Grover Norquist is against capitalism, markets, competition, profits, and Freedom Markets™ in general. Nope. Not true. We love that stuff. Corporatists (monopolists) hate competition, free enterprise, and so forth. All the anti-left screeching is pure projection, kabuki for the news cameras.
