There have been a small number (that you can count on one hard) of cars that have got into the pipeline before they were fully de-optioned, and people (perhaps reasonably) assume that because the car physically has FSD then it has it legally (as in, its on the paperwork from Tesla when sold to the dealer). That sucks of course, and Tesla has made good on several occasions, as it IS there screw up since they were careless letting the car out of their hands before the de-optioned "took" (which happens when the car checks option status with the mothership).
But I dont think its justified to take those minority cases, bad though they may have been for those involved, and extrapolate to some world in which Tesla are deliberately plotting to fool people into thinking they have something when they dont (and will find out in no time at all).
As for leasing, I've only ever leased once and there the option was either for me to keep the car ($$) or the dealer to take it back .. since I dont own the car during the lease. That doesnt seem any different to Tesla lease plans either, or am I missing something?
The fact remains, if you own your Tesla, you can resell it on the open market INCLUDING all the option you paid for, software and hardware, and get whatever resale value you can for them. Which, last time I looked, was exactly the same as every other car on the planet.
