Those same 20000 TEU container ships are famously susceptible to being blown about by winds when they loose power.
The stronger argument is that wind is not consistent or reliable enough for logistics. At least, not without doing a lot of extra math.
So I agree that sail propulsion alone won't happen at large, but it's an interesting question of how far in that direction commercial shipping can go with modern technology.
