Modern vertical farming helps reducing land-usage but runs at much higher costs.

Why? At higher milestones there are two options of how you like to proceed.
You could follow the vanilla idea of the game and intensify your trading system - or you replace agricultural areas with high density buildings. The later is my choice of game play, because i like having a self-sufficient city. And for such vertical farms are required for allowing more building space.
Since such becomes relevant at a later stage of the game, i am allowing these vertical farms from International City 4 onward. At that point in time you should have established enough high value industry for the export, so the higher costs of the vertical farms should not be a problem.
