No, it doesn't. The argument is that peer review is incompetent gatekeeping in general, and so slows things down and makes thing expensive. Also, I am countering the argument "we need journals because journals do peer review" by arguing "peer review by journals isn't clearly actually good", I am not saying "peer review in general is unneeded", as I support review by the entire scientific community, rather than journal gatekeepers.
> you fail to show how doing any peer review is strictly worse than doing no peer review
I wasn't trying to show that. I have provided plenty of arguments to show why killing journal-based peer review could definitely speed things up and so potentially make things better. I want actual organic review by the community, not by tiny groups of gatekeepers.
