"We have property everywhere and yet there are so many homeless..."
From a standpoint where you want to make things equal for people, what he says makes sense.
However, in the real world, people own stuff and can do whatever they want with it. If I wanted to and had enough money, I could buy an entire street in central London, and then let it stay vacant while homeless people roam the streets. And it would be perfectly legal, although not very moral..
Our fundamental economics are totally screwed up. How interest, fractional reserve banking and various debt instruments that create "units" of value out of thin air and then use that power to usurp control leads to a lot of mismanagement/allocation of resources.
The Blockchain fixes some of the inherent corrupt practices of our monetary system.
Its not about making things 'equal' as in resource distribution. But more as in 'equal access' to capital so that whoever wants to sell something and as long as there is someone to buy it, then you create a free market. A removal of the middle man will allow much more friction-less transactions. In that kind of a decentralized world, capital will find the best uses through open decentralized exchanges. Some people may value wars more, some removing poverty. The idea of how to allocate resources won't be decided by a few bankers, but by a more open decentralized, freer and a more democratic society.
Amir was alluding to these issues. And given the constraints, I think he did a pretty good job.
