Its just a matter of who the beneficiaries are Why don't we start from designing for the beneficiaries to be the end users? Every strategy has beneficiaries, but yours is in no way a useful criterion for design. Elminating electronic communications and commerce would have very many beneficiaries, as just one example. Enabling high-speed smooth handovers between heterogeneous radio technologies would benefit some people more than others.
