I agree with most of your points.
Despite some heavy criticism, fluctuations and scams, Bitcoin is definately staying.
Why is that ? It's because it is an Open Source project. Open source projects never die, as long as there is at least one developer who wants to develop them. Some projects get revived even after years of code not being changed, but i highly doubt that will be the case with Bitcoins, as the development will never completely die.
Until today, everybody treated Bitcoin as a get-quick-rich scheme and a way to scam other people. That was the initial level. Now, we are moving into the next level: slow stabilization. The 3rd level is, i hope, fast but stable growth.
EDIT:
Also, another argument:
No technical weakness has been discovered to this day in BTC and it is still superior to any other currency known to mankind before. Nothing has changed really.
What we are observing now is just negative parts of human nature exploiting the occasion.
