Now "Nature" (the publisher) has many journals, and many of them has a name that starts with "Nature", but they are different journals, with different teams and different qualities. https://www.nature.com/siteindex#journals-N
If you're polite and respectful to people, they respond better. Give it a try. :-)
Then anyone can correct mistakes
Is that a joke? Have you ever been in academia? Bias is everywhere. Bias towards certain hypotheses, political outlooks, methods, etc. The more senior someone is in a field, the more biased they tend to be! I've seen the founder of a field vote to reject a paper because it was "already known" because he skimmed the paper and misread it. There are entire fields of Alzheimer's research that are suppressed because they don't work with the Field's Favorite Aggregating Protein. I've witnessed people add spin to the conclusion section of a paper so that it looks less politically incorrect, and I've also witnessed that this step is both necessary and effective for getting a "dicey" paper published. Get out of here if you're going to assert that scientists are these objective Vulcan types that are "above the fray". They are some of the most "biased" and opinionated people in existence!!
Yes, did several studies and also a PhD with a Nobel laureat and some publications. I don't claim our present system is perfect; it's far from it; but I don't know a better one; thus my question: Do you have a better concept?
EDIT: Preprints are actually not a replacement, but essentially loosen the submission deadline and increase the number of (potential) reviewers. But even with this, many disadvantages you criticise still exist; the public reviewers not appointed by the publisher can also be wrong, and the outcry of indignation can be so loud that the author's superiors enforce a withdrawal of the publication.
Publishing is taken far too importantly in academia
>Reviewer are expected to have a suitable qualification and experience and no bias
But they do not. My last paper was rejected when the reviewers hardly understood the basics of the topic. And I have been assigned papers to review about topics I have never worked on

Not every edit needs to be approved
Open source with pull requests was not so bad for software quality
>There is no perfect system, but there are many worse than we already have.
The current system is especially bad. It takes to much time to find the papers, read the papers, write the papers, and review the papers
