Everyone here is imagining all the technical ways to replace publishers. That's quite feasible as you and others point out. I think there is also real work needed to solve social (people) problems, for example:
- explain to the stakeholders by preparing various text and other media about how your format/venue/website is different and better, and convince them that this solves a real problem they should care about
- solicit requirements from universities, funding agencies, various governments, about archiving and metadata requirements. Consider security, accessibility, long-term preservation, financial model, etc.
- respond to the questions and pushback from numerous stakeholders about problems (real or not) about your proposed solution, debate them in a polite and professional way in semi-public forums, converge on a solution that's acceptable (or at least not overly repulsive) to the key stakeholders. Deal with any PR backlash, response from existing publishers, etc.
- inform authors, potential authors, readers, journalists, universities administrators, students, etc. that there is a new publishing format/venue/website and that it is well managed and has a plan to be around for a long time
- coordinate and schedule a team of people to work on this with you, to figure out policies (author plagiarism, recruiting editors if needed, dealing with potential lawsuits, bad actors, copyright and IP issues, etc.)
The same way Wikipedia and Reddit manage to provide quality platforms that provide tools to address these social issues, built for longevity, and have strong community moderation.
