So I personally agree with everything you said, especially about putting the power back into the hands of the user. But do most people really care? Using your FB example, after all the crap that FB n/k/a Meta has pulled its stock is still flying high and user engagement/numbers have felt little to no impact whatsoever. People simply don’t seem to care about their privacy as much as the SMEs would have us all believe. Or, at least we only care about privacy to a certain extent.
This is very simple...a lot of people are very uneducated about many things across the globe so this would go with your view of "why would the end user care". In the example of Facebook or even Amazon the average user has no idea what is truly being done with their data other than what they may hear in circles or potentially read somewhere but even then it is above many people's heads. The reason: because it has no material impact on them or their wallets. Yet systems like Alexa auto-default to listen to what is being spoken about so they can have people annotate to improve their Natural Language Processing to improve their products.
Now when it comes to Money and impacting you personally that is a whole different story. People become educated pretty quick when it comes to taking money away from them. That is why I think people would prefer the crypto world to reduce transaction costs, take away the manipulation aspects of a centralized party, or the ease of transferring assets again with the immutable ledger that cant be manipulated.
I have been trying to learn more about the NFT and Token Space outside of just crypto and blockchain to understand benefits or if this is all a fad. It is why I have a higher investment n ETH than in BTC right now as I believe that ETH has more use cases beyond a store of value. Again, I could be wrong here but its just what I have researched.
I just bought my first NFT the other and personally I think it is completely stupid to buy a picture and pay crazy gas fees to get one that is unique to me yet anyone can copy the picture and use it as a replica. I get the Unique ID thing but what will that really mean for something like a picture that was "minted". if you provided a Unique ID on a pair of Air Jordan Sneakers to authenticate them that is immutable, to me, that has a significant value to me so you can avoid fraud in purchasing something of value. So many aspects that protect musicians putting music out there and getting paid, etc.
Again, spending $2mm to buy a plot of land in Axie Infinity in the Metaverse...still a complete unknown and baffling understanding for me.
That said, here is a good use of BAT Token and Brave Server which helps find a problem for which we all suffer from using current web browsers with ads and speed. Again Corporations using our data to work with advertisers...$$$$
