In physics at least you need to write and typeset your own papers for the most part.
Look at arxiv.org, that papers there are made purely by academics from start to finish and are already publication grade (if not better).

(That said, typesetting and writing are more and more often offloaded to academics, but there's also things like e.g. making HTML versions and system-readable versions [1] available, which is a cumbersome manual process.)

So yes, peer review is useful, but it also often happens after publication at arXiv, outside of the journal submission.
