You have completely missed the point, as usual. I don't care why people create such outputs - I'm not the one judging other people for using their money in the way they choose to use it. I'm not the one trying to apply my rules to everyone else, and censor those I do not agree with. If people want to do something you deem "stupid" with their money, then they should be completely free to do so. I think NFTs are stupid, but people should be absolutely free to spend their bitcoin on NFTs if that's what they want to do.
That's exactly my point: Unlike NFTs, there is no use case for creating this dust output in Samourai. It's pure downside to the user from every aspect (as well as a downside to other Bitcoin users who now have to compete for less available block space).
