In effect, at the start of the game, the private economy does not use truck points or rail points. While the private economy is concerned about logistics points reaching assets outside a zone's city, this is not a prtical concern for private industry at the start of the game.
I could make the argument that Transport Hubs are not particularly valuable for the private economy at all. However, it most influential to the player at the start of the game.
For all practical purposes, at some point, the player must nationalize the truck point producing asset with the 1st SHQ. It is not a real choice for the player. It is a dominant strategy. A dominant strategy is the optimal move for a player regardless of how other players act.
Start the game with a Truck Station at the location of the 1st SHQ.
If this was simply done as a trick to provide a difficulty for the player to overcome in the early game (lower truck points than provided by Truck Station I and less workers), then so be it.
