If vertical farming was more efficient then it would be cheaper.

Heres to hoping it is cheaper. Cheaper food is always a good thing.

I'd doubt it is cheaper where I live. Land, labor, electricity and water are all expensive, and we have high taxes for the services provided to us. Where I live is extremely economically productive. I'd doubt growing a few pounds of fruits could compete with producing high value services.

Other places are so efficient at growing fruit, free sunlight, free rainfall, land is plentiful and cheap, labor is cheap, and shipping is so efficient that it's better to just ship to us.
