The problem here is that, all context considered, Arrington is going one step further than just saying that the artists don't deserve compensation here. He is very clearly raising the point that artists shouldn't expect to be compensated at all for recordings ever.
Of course this is quite disapointing to me as much of the music I listen to cannot be created live by its artists but instead takes days or months to prepare. With the advancement of computers, more and more often, musical composers will be able to use just a computer to create music that traditionally could only be created by live musicians - and lots that can only be created through computers. Guess I'd better kiss that goodbye.
