I wish we could regulate the oligarchs away, but it seems to me that is precisely the right amount of regulation that allows for oligarchs to thrive.
If you regulate to protect IP owners, and basically make them rentists, you create IP based monopolies and olygarchs. If you also regulate to prevent consumer, worker and industry sector abuse, you end up with a very stagnant economy a la europe.
If you don't regulate at all... I don't know what would happen, but it sure seems interesting to me.
