No, that's simply what the media giants would like you to believe. In fact, there is plenty of freely made and distributed content in the entertainment and practical world: youtube sees more uploaded every six months than the major networks have ever created, and I'd even claim some of that content beats out the best stuff the NBCs and FOXs can put out.
If something like an automobile replicator existed, it would simply mean that it was time for our economic model to evolve: we wouldn't need billions of dollars tied up in automotive design and research. Those with a hobby/passion for it could still do it, others would have to find a new line of more useful work. But considering the alternatives here are free cars for everyone, vs maintaining the outdated model for the sake of "some poor designer", I'd forever advocate the improved standard of living across the board.
The day is coming when companies will realise it's more resource intensive and costly to protect their IP against the wave of increasing technology that spreads it, and will instead embrace viral marketing and mass-distribution of their IP instead, seeking other ways to monetize it. Look at the top innovators of this century: Apple, Google and Facebook. Apple is the only one charging it's users for a service, and then only because it costs significant bucks per unit to crank out iphones and ipads and ipotatoes. If we ever reached a stage where physical objects could be replicated as readily as virtual ones, you would see a company out in the market lead embracing the most impractical marketing strategy of all: free. Because free gives you market share, market share gives you audience, and audience gives you the one thing we will never replicate: time.
