I don't doubt you are correct Peck regarding the "importation" requirement if one transports a purchased product across state lines...but as papipeguy alluded to in his comments, no one has ever heard of it or ever does it.
The whole issue is similar in a way to automobile insurance. It would simplify things to attach the policy to the driver rather than to the vehicle. But in the case of taxes, nothing is ever done with simplification as the desired outcome.
