I strongly agree with the general gist of your post; I don’t use any social media and a piece of me dies anytime a twitter link is shared that I can’t read because I don’t have an account.
That said, I don’t think the technologies and solutions you’ve proposed will take flight unfortunately.
I’ve been very curious about IPFS for the longest time, but it seems to fit into the same category as blockchain: beautiful technology that could solve a lot of problems, yet the barrier to entry vs just doing it the status quo way is too high.
If the general public can’t be bothered having their own Wordpress blog, the jump to running a server or writing a single HTML tag is far too difficult.
I’d love to see a fully not-for-profit social media organization whose only goal is the wellbeing of users
