I share your viewpoint and frustration with "decentralized" apps. But as you said it is indeed possible by bundling your app with IPFS and using something like orbitdb/ipfslog for structuring data. I linked this in my other comment, but take a look at this proof of concept: https://www.reddit.com/r/musichoarder/comments/lrqx7m/record...

At this point the major challenges are with UX, especially for users who are not accustomed to self-hosting. I think we have the technologies and ideas to overcome the rest.
