That's an interesting perspective, I hadn't ever broken the word down and thought about it like that! However from the perspective of a native speaker, I can't imagine anyone thinks there's anything admirable about a "landfill". It's possible that it's a euphemism preferred by the local authority or whoever has to handle the rubbish we generate, but really we all know what it is referring to.
