I don't see a problem with this, in most cases, and I only sort of understand why people get upset about it. It's simple and easy (and fully legal in most states) to just design and build your own vehicle to your own specifications, provided you meet minimum requirements regarding road worthiness.
You certainly can truly own your own commercially available car if you're willing to hire a lawyer, negotiate, and pay for a license that includes whatever it is that crosses the threshold into whatever a given person considers true ownership. And I can tell you immediately that this license will cost you at least 50 times the list price of that vehicle, will not be a transferable license, and you will not be allowed to sublicense it.
It's not that you can't own your car, it's that no one is willing to pay for true ownership, because it is entirely impractical and unimportant to fully own a car in today's world.
