You have just highlighted the main fact about the www that so many technical skilled people are missing to see. Most consumers have little to no knowledge about anything technical, which is not bad at all since there is no reason why they should care. Now imagine telling those people that everyone should have their own website instead of a social media account. What a horrible and illogical thought in my opinion. Digital consumers only change behavior if something is 10x better. So from a consumer perspective, who cares about things like decentralized networks? Or Duckduckgo.com for example is probably for 99% of the www users some chinese russian inbreed virus. People started using ChatGPT besides google because it is simply 10x better for many cases, and not because it promoted with more privacy feature and less ads than google.
