NeoDoc,
You are misapplying your own analogy.
To follow your analgy, what I am saying is that children can learn the correct science to build bridges but if they learn the wrong science, they may build sloppy bridges. Furthermore, they can also learn the correct science to build bridges that are deliberately designed to fail or to build boobie-traps or bombs or FreedomFighting in the middle East to perpetuate the petro-dollar etc. etc. etc.
Can we all agree on one thing? We all believe that the NAP identifies morally correct behavior?
If you do not agree with me on the above, then forget my argument.
Let me rephrase my position.
By teaching children our Austiran economic approach [the correct scientific approach to economics or engineering], I would hope that my children develop an astute understanding of analyzing human action such that it will lead them to identify when the NAP is being violated better than their peers do – in the off-chance that it may interest them to look at morality in applying the correct scientific approach to day-to-day life. I would hope that my children do not choose to apply Austrian economics or the correct enigneering principles to design nefarious ways to screw the tax-payer or to build traps and bombs.
The mainstream schools of economics obliterate the lines in economic transactions so that it is impossible for the average person to see that we are essentially dealing in 2nd, 3rd, 4th, 5th, etc. (to infinity) order stolen goods. That would not be the case in an anti-state society.
I cite the minarchists as an example. They understand property rights the way we do — more or less — however, they switch gears for MORAL reasons when it comes to state monopolization of the money supply, justice and security. They control the morality of economics because nearly 99% of the population reflexively believe that the money supply, justice, security, the courts and the civil service are God-given immutable realities.
SHORT VERSION: I want to teach my children a moral code and the NAP is it! By teaching my children the Austrian approach, it is the best way for me to teach my children to understand injustice in our economy.
