Very Interesting post! You clearly make some points that we definitely need to come to terms with. A big part of the reason for these things that few people consider is the Paretto Principle, aka the 80/20 principle. It's a pervasive organizational principle that for some reason holds true for almost all human groups and activities. IE 20% of the people control 80% of the wealth and resources, 20% of hold 80% of the influence, etc.

Until there is something close to a universal focus that every human being gets his or her needs and requirements met without having to be be involved in a struggle to just survive (as is the case for billions of people at the moment), then this will never change in any significant way.

The great promise of blockchain to me is not, can I spend my money in such a way that no one knows about it, but rather how can we much more effectively organize society in ways that are equitable and non-punitive to everyone. We can see that as we remove inefficiencies and unecessary middle men, that enormous amounts of human energy and capital become available to be reallocated. One of the benefits of that would be of course, that individuals are dramatically less concerned about keeping what they have hidden, because levels of thievery will be universally decreased (though probably never full eliminated).

It comes down to this - do we want to redesign the world be one that is made of systems which are fundamentally built on values that are human/kind/creative/equitable or will we allow ourselves to be moved into a world that has as its core systems which are inhuman/cruel/desctructive/parasitic. I think now we are moving into the later, where as blockchain has the power to create the former. Perhaps still a little pie in the sky thinking, but we do have to think big and have real vision, because all life on earth, and the well being of all people is in jeopardy. No question about it.
