There are a myriad of ways to get size done in honest and ethical ways. How would you like it if someone burned your house down and later one excused his actions that he is sorry but he had to make space to enjoy the unobstructed view of the city. The definition of freedom is to do whatever one wants as long as it does not infringe on others' freedom and rights.
I agree with you on above. However, I want to point out that as far as games being played in the books, and all the special order types, all this is because large participants need to hide their activity as to not move the market. I think that's what @raVar means - spoofing as a part of execution strategy, not as preditory alpha generation.
