It kind of sounds like you're arguing that since the blockchain can just be ignored it's somehow less meaningful. But I'll bite:
Then the people with guns now have to expend resources to maintain and enforce those amendments. If they are not somehow just discarding the entire blockchain subsequent to their amendment, they're maintaining an every increasingly complex set of merges. Furthermore their amendment (very probably) isn't a cryptographic blockchain, so it's subject to all the problems that the actual blockchain list are not (forgery for example).
What makes blockchains unique is that they are the first example of these various records (ledgers, titles, etc) that physically cannot be manipulated in certain ways.

Their amendments are theirs. This is like saying that keeping your own accounting is worse for you than putting it on a blockchain, since someone might forge your own accounting books - it just makes no sense.
"They" can do just about anything they want. They can make their amendment. They can declare the blockchain null and void. They can hold a gun to your head and tell you to sell your NFT. They can even pull the trigger, in an attempt to make an example out of you for the next fool that tries to defy their authority. But the one thing they cannot do is seize your NFT without your volition. Not without breaking some of the fundamental mathematical ideas behind encryption.
Is there value in that in present day society? Maybe not. But there is undeniably something special about it.

That’s not true.
I mean, even if the access to the NFT relies solely on material in your head, there are pharmacological approaches, among others, that while not necessary reliable, can cause you to give up information without meaningfully willing it.
And private information will probably one day no longer exist. Imagine some kind of device that can scan the neurons in your brain along with the electrical/chemical state and somehow extract information from that (such as a memorized cryptographic private key). Let's just throw our hands up and give up on cryptography altogether.
Even a pharmacological approach is a side channel attack which no one seems to care to distinguish between attacks on or flaws with the underlying idea. When discussing the merits of blockchain technology we are allowed to take for granted its very obvious underlying assumptions. Namely that there exists private information held by a user of the system.
