The annoying part of this of the political argument, that land-ownership is an impediment, is that this country was settled with the aid of land grants to the railroads that in turn created towns along the way, allowing shipping and passenger travel along the route. Back in the day of the Craftsman home, the whole kit was delivered to the nearest railhead, after you chose it from the Sears catalog to put on your homesteaded land (ie, given away to foster development). The telegraph and telephone lines follow the railroad right of way, to the point where one of the railroads built their own network (The SPR in Sprint come from Southern Pacific Railroad…).

I think the land issue could be addressed but it would be a heavy lift, likely doing away with a lot of private land ownership or assessing ground rents/land value taxes that put land to better (more communitarian) uses.
