Earlier quoted context omitted.
From the perspective of the Broken Window Fallacy, though, buying a new window is equivalent to buying a book. Need is not a component of the fallacy whatsoever. Thus, your final statement is incorrect. pravda was not pointing out anything; the fallacy is not applicable to this situation.
To be honest, I can't work out what part of my argument you think is wrong. Can you clarify your objection?
pravda did not point that out. pravda claimed zizee was using the Broken Window Fallacy. zizee's argument and your summarization of it are not examples of the fallacy. Nor is situation 2 in your post above. The fallacy has nothing to do with something being useful or necessary.
