It's not stupid to not sell FSD at regular price if you know that 2.0 will require a more major retrofit (e.g. new cameras, other components such as new wiring harnesses, or some other components which may not be safe or redundant enough for FSD). Add to that the fact that Elon hasn't learned service efficiency yet (they can't seem to make money offering $750 annual services, cars which are dropped for for 1hr service sit on a lot for days while customers have loaners or Uber credits, etc) and the retrofit cost may actually be sky high for cars which require more than just a computer swap.
Well, you should be set, though no way to confirm FSD is activated on the older cars as everything including NOA is part of old EAP - a neat trick Tesla pulled earlier this year: "How do we deliver anything on FSD after 2 years of selling it?", "Redefine what FSD means to stuff we already delivered". Car salesmanship at its best.
