>>With the way NFTs work, the blockchain version of one would be an infinitely copyable file that just happens to have a scoreboard somewhere that says that only one person can "own" it in some very specific sense.
There are already NFTs worth tens and in some cases hundreds of thousands of dollars of ETH (see CryptoPunks NFTs) so we know people are willing to pay for something where the image is copyable, but the original can still be authenticated.
In the case of the physical copies, people can easily photocopy them or share their images digitally, yet the verifiable original still retains its value. I don't believe inability to copy the image associated with a physical or digital collectible is what imparts the collectible with value.
There is no difference in a digital Magic card and a physical one in terms of motivations to pay for one.
The anti-decentralization camp used CO2 emissions as their excuse for their wholesale condemnation of NFTs before. But now that that's gone, there doesn't seem to be anything of substance to support their blanket condemnation of them.
That you're anti-decentralization is just speculation on my part, as I can't think of any other plausible motivation for you inexplicably singling out NFTs as worthy of derision, and not centralized digital collectibles or physical collectibles.
Unless it's hosted on some WotC server where only the NFT owner can access it. But that also undermines its value, since then you don't really own it any more than someone "owns" a Kindle book: barring breaking DRM, as soon as Amazon decides to shut the Kindle service down, its either gone now, or its days are numbered.
