And the whole fake/original breaks down in the physical world. How do you tie it to the physical goods in a way that can’t be fraudulent?

Taking a step back the value of the token comes from Jack using the platform to mint it (which is purely off chain and you have to trust the platform verifies against the twitter apis correctly) and tweeting about it (again, off chain and you have to assume his twitter wasn't hacked).
Jack can delete his tweet but he can't delete a token that represents the tweet he sold. I can appreciate if you don't think this nuance matters but obviously there are some who think it does.
The same applies to physical goods. There's nothing stopping the original from being destroyed, your item being a near exact replica but if the interpretation that ownership of NFT is psysical ownership is accepted then you can't steal it and claim you are the owner without my private key.
Would there not be some liability in doing so? Legally the buyer does own it (it seems) and Jack simply has control over it.
As for the hypothetical contract not to delete it yourself, you'd probably have a good argument that there was no clear meeting of the minds - without an explicit description of what the author intended to be bound to by selling a NFT you'll have a hard time getting the courts to enforce anything about it.
Ignoring NFTs you could define selling your tweet as:
* Selling the copyright to your tweet
* Selling the right to delete your tweet
Digital ownership is a new and nuanced concept that doesn't have good analogues. Ownership through public/private keys has no analogue and also feel absurd in any analogy using safes and keys.
Digitally, it is perfectly clear:
You own the NFT. Through what is written on a tweet and a website it can be interpreted as the representation of Jack's tweet. You don't have any further owenship or rights.
As I explain in this comment (https://news.ycombinator.com/item?id=26372130) there's a nuance between owning the NFT representation of the tweet and owning the ability to delete the tweet.
or by Twitter itself if Jack is at some point deemed problematic enough by modern puritans.
