I would mention a very important point: The acceptance of people or those who want to own bitcoin is a very important point. The best product in the world can fail if people dont want it. I cant imagine that happening with bitcoin, the network is now far too strong for that and many people have understood how good bitcoin is. You write important reasons and I would confirm that. A small example of mine: I wanted to change cash from another country and went to a "big" bank (Im not a customer there). They didnt change it for me because Im not a customer and because they have to check the money for authenticity and they also didnt have that much cash on site... then I take bitcoin and no matter where I am, I can use it.
