* Various industries (TV, Print, Social Media) have effectively offered a product with complex infrastructure to the public for low or no cost by using advertisers to subsidize it. Could this be done with food or housing? Would a farm running on self-driving tractors and drones be able to feed people w/ ad-subsidized food for free?
* Lots of food gets thrown away because it's cheaper to ship it to the dump than to ship it safely to starving people. A startup could develop automation and logistics to make the costs competitive.
* Divorce rates would seem to indicate that the traditional family is not the most economically or emotionally optimum method of living/raising children. This may simply be a side-effect of increasing lifespans (i.e. 100 years ago, the average marriage lasted 15 years before a spouse died). A legal startup that offers tools for building new types of non-conventional families to optimize things like economic standing, academic performance of children, or changing employment environments.
* Micro-businesses in a box. Many businesses couple some talent or skill (e.g. software engineering, music, plumbing, creative writing) with administration (i.e. legal, marketing, accounting, invoicing, etc). Lots of startups offer to automate portions of administration, but a truly turn-key solution would allow a customer to simply input their skill, and the administration would happen automatically.
* Crowd-funding life.
----An apartment building with 20 units costs $1mm to build. An affluent person goes to the bank and puts $300k down to build it, and leverages the other $800k. Why can't 20 families each invest $15k and pay a group mortgage instead of rent?
----A single banana costs $.40. At scale, a banana is $.10. Why can't a thousand families buy all their bananas for the year through an intermediary handling the cash flow? Could they buy all their food this way and drive prices down?
