It's not hard to imagine a world in which most software is SaaS.
It's also not hard to imagine a world in which the car company decides to stop selling and start renting.
Arcade game manufacturers realized early on that it's stupid to sell a machine that makes $30K for $2.5K, so they started opening arcades. Nolan Bushnell went and made Chuck E. Cheese, and Taito was doing the same thing. Sega does it in Japan still.
I know a guy who lives on a yacht with his family, he finances trips via the dozen or so rental houses he owns. The people renting from him may never buy a house, given that building new ones here is becoming hardly possible due to zoning.
So yeah, good luck opting out when nothing is for sale anymore.
