Don't you believe in READING COMPREHENSION?
Saying we have to take the FIRST part of something without being able to consider the LAST part of something is like saying a court has to hear a case but can make no decisions.

Get your Castro issue checked. Seriously.
"It must also be observed, that individuals are not so perfectly free in the economy or government of their affairs as not to be subject to the laws and regulations of police made by the sovereign. For instance, if vineyards are multiplied to too great an extent in a country which is in want of corn, the sovereign may forbid the planting of the vine in fields proper for tillage; for here the public welfare and the safety of the state are concerned. When a reason of such importance requires it, the sovereign or the magistrate may oblige an individual to sell all the provisions in his possession above what are necessary for the subsistence of his family, and may fix the price he shall receive for them. The public authority may and ought to hinder monopolies, and suppress all practices tending to raise the price of provisions — to which practices the Romans applied the expressions annonam incendere, comprimere, vexare." (Vattel, at §255.)
There you have it - "annonam incendere, comprimere, vexare" (and throw in a little hocus pocus) and natural law quite naturally sanctions government regulation of the economy and government price fixing!

He isn't even getting his criticism straight. Vattel is referring to "Mechanics" during the Industrial revolution. This was a time period when such people were regard as we today regard our Scientists and Engineers. Their knowledge has real economic and military impact, and as such they are restricted in some cases from leaving the country without permission, or working for foreign countries.
In other words, we DO follow Vattel's advice in this regard. England did as well at the time.
