This applies when RAM is used as temporary cache or something that can be instantly freed the moment it is needed otherwise. This doesn’t really work for justifying higher RAM use by KDE, unless you would never need that RAM for anything else anyway.
I use KDE because it is good, though. Also I don’t think KDE even uses more RAM than other DEs that are designed to be lightweight. Last time I compared, it used the same or less memory as LXDE.
