The work itself is completely meaningless though. The only reason the proof of work is worth anything is because people place a value on bit coin, and bitcoin relies on the proof of work. So the proof of work's value is dependent on bitcoin, not the other way around.

Proof-of-work systems have nothing to do with the "meaningfullness" of the actual work being done. The work just has to be difficult. Hashcash existed long before bitcoin, so your last sentence is incorrect. In fact, Bitcoin is itself based on Hashcash, and the idea of using POW as a means of exchange also predates bitcoin.
