"This guy" is a Nobel Prize-winning economist. He might be wrong. He might be speaking from ignorance. He might be in mental decline after a brief period of brilliance decades ago. But a claim that he's an idiot probably needs more evidence than "he disagrees with me about whether Bitcoin should be legal."
"Nobel Prize-winning economist Joseph Stiglitz said “bitcoin is successful only because of its potential for circumvention, lack of oversight." - this statement demonstrates a profound ignorance of the subject matter. Bitcoin provides a way for individuals to make secure transactions across distances without the need for a third party to verify the transaction and that's why it's successful. What lack of oversight is he talking about? It's open-source! It could hardly be any more transparent.
