This misses the crux of the problem. Why would we grow food in our basements if we do not need to? The biggest problem with hunger today is not lack of food production but massive food waste and poor food distribution. The choice here is not between depleted oceans and starving people, the real choice is between depleted oceans and not wasting food.  

Your comments about me being a Malthusian relates to me pointing out the massive waste of perfectly good electronics, most of which are produced in China, in order to satisfy the DRM wants of organizations such as the MPAA. The link between attempts at intellectual property protection and ewaste, become clear when one finds out that one has to buy a whole set of new electronics just to support the new DRM for 4K Video, just as people had to replace their electronics just to support the previous DRM for HD video. Buy the way the new 4K video DRM has already been cracked, http://www.digitaltrends.com/home-theater/hackers-pirate-netflixs-4k-streams-for-the-first-time/ so now we throw out our electronics and buy yet again a new set? If we stop this needless waste we can have both the pristine forest and the SUVs, with both sides of the "tree hugger" debate in harmony.

Another example: Of course distributed storage is incompatible with preventing copyright infringement. It really does not matter if the distributed storage consists of a crypto currency based or solution or people storing the information on 5.25in floppy diskettes and sharing the diskettes with each other via sneakernet! Don't copy that floppy. https://www.youtube.com/watch?v=up863eQKGUI The only way to prevent all copyright infringement is to create an Orwellian super state where every bit of information is closely controlled by big brother and every digital device behaves like the Telescreens in 1984.  By the way current devices such as Apple's IOS devices and Microsoft's ARM (Windows RT/Mobile) devices meet all the surveillance and control specifications of the Telescreens in 1984. They are also somewhat effective at "protecting intellectual property".

The fundamental reality here is that protection of intellectual property is at a very basic level incompatible with both:
1) A free and democratic society where people enjoy personal freedoms and civil liberties
2) A clean and sustainable environment.

Edit 1: In order to protect "intellectual property" effectively, the Orwellian super state would also have to destroy the world natural environments and replace them with wastelands of discarded electronics.
Edit 2: Anonymous crypto currency such as Z.cash or its competitors will make enforcement of "intellectual property rights" even harder than it is today. So one may as well accept reality and change business models that belong in the 19th century rather than try to fight technological change.
