Peter raises a good point. And one might add that, as Smith makes clear in Book V, that "vast spontaneous order" is built on a foundation of well-articulated and enforced (by government) property rights and contract. Indeed, when Smith wrote, English common law had by far the most sophisticated legal framework that had to that date ever been articulated to frame market activity. This included patent and copyright, property rights in good will and trademark, the ability to enforce "non-compete" clauses in sales contracts, etc. A contemporary of Smith, the great Chief Justice Mansfield (King's Bench) was acutely aware of the importance of law to sustaining a dynamic economic system.
