Are you really suggesting that all native speakers write perfectly and their writing never needs any corrections whatsoever? I consider that far from the truth for any native speaker of any language and I would of never assumed that.

Everyone's writing can be improved. However, for native speakers, and especially if they have the level of education where they are producing original research, it would be a rare case that the writing was so bad that the science being communicated was undecipherable.
