I will admit that this image presents a very interesting way of presenting the matter in front of us, and part of the issue is that value is being stored in asset classes that are very inefficient as storage of value and even inferior storages of value. 

Even if bitcoin sucks some of the value out of several of those other less efficient/inferior storage of value, most of them will still hold some value in terms of their utility value and/or still retain value because people might conclude (perhaps wrongly) that they are better storages of value than king daddy.  So maybe the addressable market would be some kind of fraction of the total value of some of those other assets..

Maybe creation of an explanatory table might be helpful to better attempt to illustrate the point and also allow others to tweak where they might find better ways of figuring out the matter.

I am just doing a quickie SOMA valuation of the inefficiencies, so feel free to tweak my valuations - including my multiples of inefficiencies...

But even with this ballpark figure, we get bitcoin to be valued around 822x of today's prices..
