By providing a set of tools that allow (but not require) disintermediation.

Sure. It also blocked them. It also has created massive costs to people. It has also created Surveillance Capitalism. It employs thousands of people whose sole job is dedicated to keep its users addicted. It is creating a society of people who can "connect" with anyone on the other side of the world, but who get anxiety attacks if they have to talk with their own neighbor next door. It is destroying all chance of civil discourse, making groups increasingly polarized and isolated.
> that have much more value for people than idealism
To some people. Good for them. When it works, it is great. The question is: what about those people who don't get to enjoy these benefits? And can we get to provide this value without having all this collateral damage?
> (that doesn't even work!)
It works for some cases, and it works for some people. There is no technology in human history that was "born" perfectly ready for mass-usage. And there shouldn't be.
I'm not advocating here that we should all be dropping the systems and institutions that work, just to adopt something for the sake of "new tech". What I am saying is that there are whole lots of groups who are not being served by the current systems and institutions, and that we can do more than collectively shrug our shoulders and/or attack those who are attempting to create a solution.
