I'm confused 
First you argue...
I think Bitcoin can do both, and that these different aspects of Bitcoin actually reinforce each other. I also do not think Bitcoin will become a world reserve currency without experiencing mass adoption as a currency for the people first, history also certainly supports this theory as well.
to which I reply...
It doesn't.
hdbuck, always the sharp guy, understands what is being insinuated...
did "teh mass" ever had gold in any meaningful way?
hmnope.
By now I'd expect your are still clueless as to what it is I'm trying to lead you to so, to be clear, the argument goes:
Something does not need to be "mass adopted" for it to become a "world reserve currency".
It just needs to be the predilect form of money for
relevant* economic actors in the society. Case in point: gold.
*masses != relevant
