This is the natural imperative. This is the true genius of design for disassembly. These strategies not only appeal to the ultimate recycler, they have benefits to the original producer that are so significant, they usually pay for the costs of DFD conversion. Fewer parts also mean lower inventory costs. A product that is easy to disassemble is easy to repair or modify.
Products can last longer because only a failed subpart needs to be replaced.
Waste can be reduced if a large product does not have to be scrapped because a small part fails or becomes obsolete. Regionalized custom production becomes more possible if modifications become easier. Because design for disassembly has payoffs at both ends, one might assume that there would be no resistance to this clearly superior design strategy. There is all sorts of resistance to goes far beyond a producer's need for product immortality. Change involves risk.
