Hell no, at the individual. However to maintain a society of individuals, norms are very useful... cultural "glue" (or something resembling the middle of the social 'curve'].
For people who use what would be considered technical language, the lack of a normative (standard +-) meaning is a hinderance to communication of key concepts, which could be intentional for a variety of different reasons and innumerable motives. But I believe it would, due to causing inefficency in that *communication*, create a net negative effect on the discussion at hand [...if any mutually 'productive' [heh!] discussion of: 'productive' vs 'unproductive' was a point of interest, it would be best to have terminology that holds still for more than one debate [:>]
