I think it is not in anyone’s best interests to lessen their ownerships rights to maybe save money. Their choice is also bad for me in that it shows companies they can to it too and could become the norm.
While yours are valid concerns, that type of restriction works only on specific items. I don't see a car manufacturer pull the same stunt on a mass production car (or any other mass production item for the matter) because the problem this try to solve does not exist in the first place, maybe Tesla just think (true or false that it can be or based on the data they have) that the Cybertruck will be some sort of "status symbol" which would attract scalpers or the like of them.
In the end this is a battle Musk cannot win: he will be damned if he do (to ban resell in the first year) and he will be damned if he don't (and thus allowing scalpers). He can only choose why he will be damned so he choose a way that maybe is more friendly (or less enemy from your point of view) to the consumer.
If a manufacture has a good reason to not sell to someone that would be fine but it is none of their business what colour I paint my car, or who I can resell it too.
I can agree with you, but the fact that the manufacturer put these restrictions and people still buy their cars means that maybe it does not really matter to the buyers since having the car is much more important that being able to repaint it pink, in their view.
