It might be that the idea is too complex to be viable or useful. The graveyard of technologies created in the past decades stretches to the horizon, so if something doesn't work after 10 years doesn't mean it will work in the future. This is kind of obvious.
Specifically with blockchain my intuition is that, if its main selling points - immutability and decentralization - are already invalidated in the early days (10 years that is), the chances that it will recover are slim.
Complex tech tends to centralize to become cheaper. Also immutability is very problematic in terms of the right-to-forget and also in terms of illegal content and illegal operations.
Email's purpose and utility was super-obvious from day one, we just had to figure out how to make it more secure. Notice how email too became centralized, however.
