Could you? I don’t find that at all obvious.

What you can't do is sell the rights to the modified work, since they're in addition to the original work. When/if the copyright in the original expires, then you can (and you will have your own copyright in the modifications if they're substantial enough).
Crucially, you also can't make any copies of the modified work and sell or distribute them, so your derivative will be a legally-enforced one-off.
It doesn't mean that you can't profit from your modification of another's work (maybe someone will pay for your marginalia), but it does mean that you can't profit from the unauthorized duplication of another's work while their copyright subsists.
If you have a personal created copy of a copyrighted product which you do not have the rights to, you don't have a right to sell this copy right? (Specifically talking about the copy and not the modification)
You buy a physical book (also called "a copy of the book"). You don't make the copy, you buy it from a legitimate seller.
Then you can modify that physical book, and sell it again.
If you want to sell a second one of the work you made, you need to buy another physical book (another "copy of the Hobbit"), modify that physical object in the same way, and sell it again.
You would own the copyright to your changes, so no one else could modify "the Hobbit" the same way, and no one else could publish instructions on how to do the modifications yourself.
Reading the law, it's still not obvious to me that that would be legal to sell, and I kind of doubt there is any case law on this point.
You have the right to sell both, one as owner and one as owner and creator. But you only have the right to make reproductions of your own work, which means if you want to make more copies of the complete derivative, you have to buy new authorised copies of the original. You don't have the rights to make your own copies of the original to modify and sell.
But the copyright on derivative works is held jointly by both authors.
Do you have any citations of case law backing up your interpretation? I'd be really curious to see if a court has actually ruled on this.
As for the sale of the physical modified-but-uncopied original itself:
In the EU, this is permitted under the equivalent to the first sale doctrine[2, p880][3, footnote 7], which covers all IP, including trademarks and patents. There's now some weirdness around Brexit which is what document [3] is all about.
The case law actually goes both ways in the US because the concept of derivative work is not conclusively defined in statute:
* It's OK: Lee v. Deck the Walls, Inc. [4] aka Lee v. A.R.T. Co.
* It's not OK: Greenwich Workshop, Inc. v. Timber Creations, Inc. [5], and also Mirage Editions, Inc. v. Albuquerque A.R.T. Company
These cases are almost identical and one on each side even involves the same defendant, but have opposite conclusions. So as usual, the US gets weird and jurisdictional with it. So, indeed, my original comment is actually wrong in that US First Sale Doctrine isn't guaranteed to apply and mostly seems to depend on the circuit you get sued in. TIL.
There are additional rules if the original is limited edition or certain types of art (usually "visual" and "limited"):
* In the US, VARA means certain creators can, in some cases, sue for damages if you destroy or modify their work, even if you own it
* In the EU there's the Resale Rights Directive (which codifies what is often called droit de suite) which gives royalties of each sale to the artist (but this right cannot be transferred or inherited)
