>The limits of NFT are simple : when you have no power, you can't check it. It isn't tied to whatever object it represents, so the object can move about without it, meaning that the NFT cannot prevent moving the object.
I suspect you're somewhat missing the point the article is trying to make.
The thing is that it's the NFT which is unique.
Sure, you can clone the original item as often as you want, and each copy will be identical to the original. Or you could even clone it and edit it to produce something new.
(In fact, every time you transfer a digital item, all you're doing is sending instructions on how to make a copy and then deleting the original. There's distinct shades of the old philosphical question around "I've replaced the handle three times and the blade four times, but this is still my axe" in all of this...)
But it's the NFT which says "this particular arrangement of bytes is the original arrangement". And it's the ownership of this statement (or more precisely, the first formal declaration of this statement) which is being given value.
Personally, I think the value of this statement is pretty low. On the other hand, I tend to think that about a lot of high art ;)
