I’d agree with everything you’re saying if the cost of inspecting the car for rejoining the network wasn’t $2000. It should be a relatively simple inspection/test of the relevant systems and should cost 1/10th that.

Also, if the vehicle is flagged by Tesla as being salvaged, it should be made obvious somewhere in the vehicle, in the same vein as a check engine light, or more realistically an error message on the UI screen. It should not be a surprise to the driver that the car won’t charge (let alone an unsuspecting buyer.)
