Thanks to Gunning for his try at my question. And my apologies for   
its lack of clarity; I should have left the words in parentheses   
out--a different issue. In the simplest sense all I want to ask is if   
"economic interaction" in your definition (or Mises's) is only the   
interaction, exchange, or trade, in markets, or does it include   
production, the transformation or reworking of something material   
into something else material?
