There are some classes of products where uncertainty is desirable. For example the unpredictability of sports game is crucial to its mass appeal. A predictable match can never be a crowd puller. It is in the interests of leaugues to perpetuate this uncertainty by following a platform strategy, encouraging intense competition between the teams and thwarting a clear winner.

Even in the EGS financial market the uncertainty in the Natural gas business is very desirable. If Natural Gas was not a risky proposition then Investment Banks would be allowed to dabble directly without the intervention of EGS.
