All of those things are true today.
The question was: >Should closed hardware (that owns its entire stack) even be legal to sell?
And the answer to that is: obviously it should be, if you care about competition and innovation. The only people that disagree with this are the tech people who have had problems with Apple's business on ideological grounds for decades (people like Richard Stallman and saurik).
But outside that one particularly small constituency, there's no good public policy reason to actually make it illegal, and plenty of reasons not to.
>The U.S. Librarian of Congress ruled on Monday that consumers who circumvent digital protections on smartphones to install unapproved applications—a practice often colloquially known as “jailbreaking”—for noninfringing reasons should be exempted from prosecution under the anti-circumvention section of the Digital Millennium Copyright Act (DMCA).

I'm not sure why you're putting this in terms of iOS, since many Android devices also ship with a locked bootloader.
>there is no reason why jailbreaking a device is inherently possible
Any iDevice with an A11 or earlier has an unpatchable bootloader flaw that absolutely makes it inherently jailbreakable. Apple cannot prevent you from jailbreaking those devices, nor can it patch the flaw with a future version of the OS.

This would not apply to something like Prima Cimea, nor a John Deere Tractor, or 1000's of other things.
Also the wording of the exception bu LoC was very open to interpretation and not as powerful as people commonly think
Ahh, I see the problem - thanks Osiris - there are 2 questions, each of them opposite.
> Should closed hardware (that owns its entire stack) even be legal to sell?
and
> Yes, it's legal today but should we make it illegal?
Good thing I'm not a lawyer!
His answer: Nope.
