More goods, but less control. When the food has to be smuggled in by the same routes by which Hamas smuggles weapons, then of course they have control. If there was free trade between every Israeli and Palestinian who wanted to participate in such trade, then Hamas would have to commit overt terrorist actions in order to disrupt it. The present situation gives them control over Gaza on a silver platter. The fact that the platter is engraved with the words "we really don't like you" doesn't seem to make much difference to them.
