My opinion (well, the part that goes beyond the "wealth by excellence" aspect) is based on the idea that societal problems can't be solved by technology, something that I firmly believe in. The same kind of people who found ways to exploit the current system will find ways to exploit whatever else you give them. Yea, let's try to make it harder for them, I'm all in for that, just let's not fool ourselves thinking we can get rid of all evil and greed by creating a Magic Network
Most importantly, let's not try to get rid of super useful features just because we can be sure somebody will misuse them; those somebodies would misuse anything else, too, but life will be much better for most if we refuse to listen to those fears.
EDIT: Interestingly, one of the most over-governed societies of the West, the United States, is also one with the hugest inequality ratings. Just a hint for how much trying to solve problems help: the more the rules there are to protect the majority, the more ways there are for the minority to game the system. Just my theory, don't trust it too much
