I stand by my ludicrous statement.  Of course 71/2 billion people could live in a state the size of Texas, I never said how long they would be able to live.   I probably do not have the social engineering skills of a Stalin or Mao or even the great Pol Pot but I would never force the Worlds population to live in Texas.  With the addition of a few billion rafts, the entire population that I rule would live in Hawaii. Finally, we will all live in Paradise.  :)
