That's a bold and provocative statement. I'd feel a lot better if the author actually proposed some way of ending "money management as we know it" instead of just throwing the blurb out willy-nilly.
Nobody disagrees about the premise: markets will always seek to find loopholes in the system and in the human condition. Some people see this as a source of growth -- after dozens or scores of such blowups, beginning way before the Dutch Tulip Bubble in 1637, markets have continue to grow and become more and more sophisticated. Whatever the fundamental flaws, it's obvious they haven't prevented outstanding growth over the last several hundred years or so.
To propose a dramatic new solution, it's your job to make the case that the benefits outweigh the drawbacks. Otherwise it's like speaking out against eating because of all of the cases of food poisoning -- you're missing the point.
