Betting on my neighbours house?

Lynn Stout's point about Goldman Sachs' Abacus Mortgage Derivatives Deal (New York Times) illustrates the need for stricter derivatives regulation:

"...much of the blame for investors’ losses in the Abacus deal can be laid at the feet of an obscure statute passed by Congress in 2000, the “Commodities Futures Modernization Act.”
If we allow the unscrupulous to buy fire insurance on other people’s houses, the incidence of arson would rise sharply. In one dramatic move, that act eliminated a longstanding legal rule that deemed derivatives bets made outside regulated exchanges to be legally enforceable only if one of the parties to the bet was hedging against a pre-existing risk."
