Ehh sure, but then websites have no incentive whatsoever to publish content. The future you're describing is one where:
- Only the big players operate (more centralized)
- Only walled gardens, because who would publish content publicly for everyone to ingest and then modify, with no gain whatsoever?
- More arms race to create DRM to prevent ad blockers, or deals with browsers not to tamper with specific sites (so, more centralization)
What you're proposing makes no sense, and will only deteriorate things further in the long run.
