People use plants more for food than for any other purpose?

For anything I would prefer for money, even I use Farming for money by developing plants and fruits. Some of them use for business purposes like Wood and pulses to sell in the market.
If it is indoor gardening then peopl have to use for Food only rather than their is no way to cultivate for business purposes. Cannabis can be grown but it is illegal in almost countries so people wont grow such type of plants.
