You could say the same about abandoning capitalism for another type of economy wholesale.

The point is that there has always been regulation because when we have tried removing it (look up grain shortage in France during the mid to late 1700's due to export deregulation) and it ends up the same. Deregulation isn't the answer.

There is no "seeking perfect deregulation", only the admittance that deregulation cannot be part of the perfect solution.
