And this shows you never even took the time to read my post.  I said the results appear to hold for all sets of rational assumptions I've come up with to date.  In the example above, Bob implicitly assumed that the chances that bitcoin goes to zero was 95%.  Even with these conservative assumptions, bitcoin was still a useful store-of-value tool for Bob that helped him to reduce risk. 

Please, find a set of reasonable assumptions where it wouldn't be wise for Bob to move at least a small portion of his wealth into bitcoin.  Argue your case mathematically.
