What he hits on is that there is no scarcity anymore. Media is reproduced and shared freely and instantly, because that is the nature of the internet. The 'pipes' (expensive, physical means of distribution) the recording industry pumped music through for decades have now dissappeared and have been replaced with an open environment. Anything that tries to close that environment is just trying to create artificial scarcity.
It's true that media costs money to produce. And the publishers can still charge for it, if they make the distribution model convenient (or not). But that is still a one time cost which promotes the artist. And let's not act like artists are going to just stop making media if they don't think publishers are going to give them a big payday. They aren't. The more likely scenario is that the distribution will shift to being handled by the artists and that money will be made through concerts and merchandise. Downloaded music will be paid for sometimes, but mostly used for advertisement.
