I know almost nothing about indoor farming, aeroponics, urban farming, etc - but I get the feeling that people think its better because it appears clean. Farming and dirt is dirty, and indoor/urban farms/aeroponics are shiny and clean.
Of course being dirty has nothing to do with global warming or the environment, but that type of analysis is much more complicated than "looks clean!"
