The longer I persist in my negative view, the greater will be your fun when I will be finally proved wrong. 
What would take to "finally prove you wrong"? [ ... ]

Without wanting to trigger another 20 posts about my person, let me clarify that my skepticism is due to several reasons, including some political and economic obstacles that, in my estimation, are impassable and cannot be removed by any actions of the bitcoin community. The estimation depends on probabilities that I assign to certain future developments and reactions, and my understanding of how the world works; opinions, yes, but opinions which I have construed over my lifetime, and will hardly be changed by a few arguments and statements here in this thread. Obviously most people here have different estimations, and I do not hope to change their opinions either. Time only will tell who was right.
