As others here have pointed out, it undoubtedly only makes economic sense in a few niche scenarios right now. Premium hyper-local urban boutique veggies used in small quantities, or perhaps supplementing MREs in very remote, isolated military/industrial compounds (possibly including Mars?). However, if we were facing the specter of a global nuclear winter - or similar effects from a large asteroid impact, ground/water pollution, etc. - I think something would be worked out with regard to the 'cost of renting' large indoor spaces.
