The sales pitch would be the same now or in your hypothetical. Ham radio is about self education in radio, electronics and communications and that hobbiests need some spectrum to be able to design, build and test their own work and communicate with others who do the same. There would be no commercial transceivers allowed, no power above 100w allowed, a basic safety and operating procedure exam followed by building your own transmitter and making a contact with it, code would be mandatory but not examined and HF only. To keep your license you need to have X number of confirmed code contacts per year, say 50, even if they are at 2 wpm. Use it or loose it. My ham radio would not be an elite, it would be a passionate.
