That's not how I see it at all. Once Jack has been shown to be willing to oversell himself just to make a quick buck, it will immediately devalue everything associated with him, including the original NFT. You're buying into the quality/credibility/longevity of the creator here, and once it's shown he's a shill there's not much reason to value any of his original "work" highly.
I am open to being wrong, but it still boggles my mind anybody could think NFTs are anything other than a scam. At least bitcoin had lots of legitimate theory to be used as an alternative to currency, even if it only ended up being an investment alternative for gold. An NFT is like trying to sell art without actually having to create art.
