I think you should think Blockchain when you are talking about bitcoin, and the blockchain system can be used for many thing, think Internet 2.0 (what internet was 1990 and what it is now) .
I know that this doesn't answer your question precisely, but I think if someone had such a precise answer he would already been working on making it to something real by now
I tend to agree, to the masses Bitcoin is just numbers in an account. To the few it's blockchain technology.
The fact that Bitcoin functions as money underscores its potential is areas such as law, politics and even religion.
If we're going to expand into space and have populations in the trillions blockchain technology will be invaluable.
