"Transactions are never needed with a fully normalized model": I just don't agree. Fully normalized most likely means many tables for everything, and transactions are needed to maintain consistency. "you denormalized your model because your db engine's performance sucks": you're most likely to denormalize because joins are costly no matter what DB you're using. "the transactions will probably just make it worse": denormalization is most often used to reduce the number of operations (so transactions are unlikely to make things worse). I agree about the amount of garbage in the article though.
