I don’t think jkaufman meant we should use familiar-sounding words with unfamiliar overly precise meanings, but rather that we shouldn’t get in the habit of using unfamiliar overly precise concepts even when we don’t really need to (“unfamiliar” here meaning ‘unfamiliar to most audiences’, not ‘unfamiliar to the speaker’, of course).
