Not really: the Enron fiasco happened because the government reduced its involvement, deregulating the power grid, and gave actors like Enron, Duke Energy and others the ability to manipulate the market, causing prices to swing wildly. California saw an 800% increase in wholesale energy prices. You object that the retail rates were set by law. But consumers could not handle that 800% increase; most people can't handle an unexpected expense of a few hundred dollars. Utilities weren't obliged to provide power when things went to hell, they imposed rolling blackouts. They had to.

With gasoline, you can wait and shop around; if a station tries to gouge you you can see if you can get a lower price down the block. The power grid has to be balanced on a continuous basis, and if it's out of balance, the grid operator has to obtain power immediately.

The power grid requires careful management. Call that "regulation" if you like, but it isn't optional.
