I think you might have misread my intentions. First of all, I'm not opposed to philosophy. If I were, I wouldn't have bothered writing hundreds of philosophical articles since 2011, after I left academic philosophy (link below).
For me, the idea of philosophy as a fraud is somewhat facetious. My point is that philosophy seems like a fraud from the vulgar, unreflective perspective of the masses, since if they cared enough to read philosophy, they might become seduced into a form of study which undermines their treasured delusions. The result of the "fraud" would be their existential angst, like the emptying of their pockets.
(This is well-illustrated by the trajectory of the Cypher character in the movie The Matrix.)
And as I say towards the end, philosophy is only the messenger and therefore shouldn't be blamed for the unpopularity of its content.
I understand that philosophy isn't unremittingly negative. For example, Aristotle tells us how to be happy by being virtuous. But in the big picture, philosophy isn't an ally of conventional society. For example, philosophy opposes popular religion. That's largely why Socrates was executed, according to Plato (although the true reasons may have been more political). Real philosophers end up being skeptics, cynics, or social outsiders who are repulsed by society's grotesque pastimes.
