For some products, it's viable to sell replacement parts. For example, I have an Ankarsrum blender. The main engine is built to last, but a lot of things are meant to be replaced after some use. They, probably, don't cost as much as buying the whole new blender, but they still generate a revenue stream for as long as the product functions. Similarly, Kuhn Rikon pressure cooker: it has some parts that will need replacing every few years. These are, probably, not the best options in terms of revenue generation, but they are options. Sometimes it's possible to sell some kind of service that accompanies the product, or maybe some accessories... However, they aren't available for all sorts of equipment. Some equipment is just too simple to try to organize it in this way. Maybe we just need to accept that some goods will never be able to benefit from economy of scale and will have to adjust our expectations to the price? :|
