There is a great deal of debate over nuclear power, including whether we should use it or not, where plants should be located (NIMBY - notinmybackyard is a common theme).
Mr. Buffett argues that normal investors should not necessarily be able to find out what professional investors are doing, especially while they are still busy doing it, reminding me a lot of the NotinMyBackYard situation.
Setting up deep-water fish farms in the U.S. would require a hefty budget for defending against lawsuits from NIMBY (Not InMyBackYard) activists and competing on-shore and near-shore fish farms, as well as paying an army of lobbyists to fend off opposition from states like Alaska and Maine where fishing fleet interests have considerable political pull.
