You contradict yourself. If this is not news, but an opinion piece, then it requires - according to you - paragraphs in order to "express more complex thoughts in an attractive way."
But I disagree, anyway. The writing of both news and opinion is improved by using paragraphs. They improve comprehension and speed up the process.
A perfect example of why paragraphs make prose easier to read.
I have written a few times to newspapers who insist on following a policy of 'every sentence is its own paragraph'. Their response is always the same: the "average reader" cannot cope with dense paragraphs (paragraphs with more than one sentence, apparently!). Au contraire, paragraphing helps the writer to keep associated ideas together, and it helps the reader by showing the logical flow of the writing - especially if there are good transitions between those paragraphs.
