Yes, we can live without indoor maps, but we're suffering through a lot of inefficiencies just because we don't know yet that there's a better option.
I want indoor maps because they can help reduce healthcare costs. It costs us all money when people get lost in hospitals. While environmental signage helps, it's often not sufficient. Visitors end up interrupting doctors and nurses to ask for directions. This directly costs the hospital money (leads to higher personnel costs), and leads to a poor customer experience (affects the recovery process for patients and families). It is surprising how many people get lost in hospitals: http://twitter.com/lostinabuilding
In addition to navigation, there are uses for facilities management, inventory management, real estate sales, and analytics on how people use buildings. I'm a big fan of using data to improve human efficiency, and these can help save time/energy/money.
For retail environments, indoor maps present targeted advertising opportunities, which can lead to more efficient advertising spending for brands and retailers, and time savings for consumers. This is part of why Google is so interested in indoor maps.
Indoor mapping will be incredibly useful for those who are disabled. Knowing where to find ramps and elevators is great for mobility and for safety, but I think that for a blind person the possibilities are even greater. Being able to navigate a building independently using an application on one's phone, for instance. Maybe Google's indoor maps won't be the end-all solution, but will hopefully get institutions thinking about the possibilities.
