Probably they would need to actually put “free” into the free trade agreement for it to really work otherwise it’s pretty much the SOS.
You've nailed it! The so-called "free trade agreements" that countries are wont to negotiate these days are anything but free trade. True free trade would happen only when the government said to go ahead and trade what you wish with whom you wish.
Having to hire a team of lawyers to sift through several thousands of pages of legislation just to try and make a buck is hardly free trade.
