No weeds, no pesticides, very efficient yields in terms of fertilizer etc. year round growth.
With the advantage of a indoor environment being easier for robotics.
Even if you need to do some prepwork like levelling paths for a robot to traverse, that's still cheap compared to a building.
But if America and other first world countries think it’s important grow food at home this is a way of making it more competitive.
Frankly indoor farming is a very Dutch fad imo that would work well for countries with the Dutch economic conditions and stability. I could see it becoming more relevant for countries in the Middle East (who have already begun inviting Dutch farmers in droves to study them), Singapore, and possibly even some African and LatAm countries like Ethiopia, Costa Rica, etc.
