It's not an issue of simply having scams. The issue is that, by its very nature, the ratio of scams to legitimate functional work is likely 1 million to 1, and the entire ecosystem does not only revel in this, but actively encourages even more scam-like behavior. This all stems from blockchain as a concept's decision of baking in valuation to EVERYTHING.
It's the purest distillation of the "greater fool theory" in human history.
I'd rebuke your framing of leaving the morality of it aside. The more valid framing of a debate for new technology should be to prove that there are non scam-like applications of the technology that are superior to currently existing ones.
'blockchain' doesn't have any point of view on whether something should be 'NFT'-ized or not - it's just a technology. That's like saying FTP encourages child pornography because it can be used to transfer files.
As in most things, the culprit is not technology, it's people. It's entirely possible to ignore the clear rugpulls and scams and just focus on the technically interesting parts. Quite a lot of people are quietly doing just that while everyone else is busy trying to scam each other and/or be religiously opposed to what amounts to a distributed database synchronization mechanism.
