Very similar to posts we see about blockchain today. I think we all know how this well end.

This is the pick about the internet and the government how takes the bitcoin as legal or not. This is the similar thing to have the in this imgur file you have shared. As you see this as the evaluation of the market has been seem like how government works now.
There are people invest on mining and trading who are from the government side only as i see those people in my country.
I believe government and bank will use atleast private blockchain ledger to save the funds and other works for the security issues.
