Yes. I think Peerdium is not at all necessary for 99% of the use cases. You can just use a normal publishing platform. Peerdium can become useful if you don't want a single point of failure. That is anyone can spin up Peerdium servers from source code and the links would still work as long as someone is seeding the content. Also nothing is stored in a server. So if you want to share some content that you don't want to get stored in someone's private server then Peerdium can be used as well.
