What do you think about free trade as it related to Adam Smith's perspectives?

Adam Smith believed that every other commodity is finally measured and determined by ...the average money price of corn. Smith thus maintained that work (or something akin to it, such as our daily bread) provides a sensible index for determining how much other things are worth to us.

Quoting Adam Smith, "nothing, therefore, it is pretended, can be more disadvantageous to any country, than the trade which consists in the exchange of such lasting for such perishable commodities. We do not, however, reckon that trade disadvantageous which consists in the exchange of the hard-ware of England for the wines of France; and yet hard-ware is a very durable commodity, and were it not for this continual exportation, might too be accummulated for ages together, to the incredible augumentation of the pots and pans of the country."

One needs to remember that Adam Smith was seeing the world of the an earlier century, a period inwhich the world economic can be discribed as the mercantile system.What do you think about free trade as it related to Adam Smith's perspectives?
