Our dream is not about expensive bitcoin, but about using it everywhere. We don't care how much someone can earn on this, if the work is paid not in dollars per hour, but in bitcoins per hour.
I can agree with your words but deflationary nature of bitcoin which makes it more expensive with time is also important in some way: you can not worry about if your holdings will depreciate and if you lose your pension or smth like that. So it is so easy holding bitcoins and being calm that it is a very important part of bitcoin for me. It is not important that it can grow up high or not, it is important that it will not depreciate.
And as the years go by and bitcoin keeps getting more expensive while fiat keeps losing value it becomes more difficult for governments to convince their citizens to not invest in bitcoin when the benefits of doing so are so obvious.
