I do not see the point of this post. Yes, you outline some cons and pros, but is that what really matters? For me, what matters is if it has legality and if it is readily accepted by everyone. But for now, those are not yet true in bitcoin.
Bitcoin can still be considered to be very young therefore its adoption is not yet that massive...but hopefully as years go by people and organizations can see its real value and would want to be a part of the Bitcoin bandwagon. There are many obstacles and opportunities as well on the road towards Bitcoin success. I am sure that fiat and gold will still be here to stay but Bitcoin can be moving upwards too. Time is coming when big institutions and even governments would choose to ally with Bitcoin for different grounds and reasons and by that time we can see Bitcoin rise as the best star in the world of finance and international commerce.
