Study history. Tractor businesses have operated successfully from the 1930's through the 1990's using this model. Those tractors are still running and still serviceable. (I've run a Farmall Model H from the 50's and IH-576 from the '70s as recently as five years ago... they are built to last and parts are plentiful or easily reproduced... and International Harvester is still in business (maybe under the Case name now.)

These subscription-based and planned-obsolescence fads are experiments that will run their course. In the end, business will thrive where they meet consumer demands, not because their business model was proposed in some boardroom.
