All in good time.
The thing is, if you imagine Bitcoin going mainstream, it pretty much automatically goes all the way. Once everyone is using and trusting it, it becomes almost
idiotic not to use it for stocks, insurance, contracts, etc. In for an inch, in for a mile. I realized a while ago that there are no half measures. If Bitcoin succeeds for even one of its core envisioned functions on the world stage, it won't stop until it has changed everything even remotely connected to finance - that is to say, just about everything.
Irdial wrote in 2011 about just one small function of Bitcoin, the payment network aspect:
The potential of Bitcoin is obvious to those that are intelligent, that understand computers and software, who have some knowledge of the present state of and recent history of the internet and the problems of money transfer online. Anyone who knows what this really means is awestruck, gobsmacked at how everything is about to fundamentally change.
The scope of what is about to happen is beyond what I think any person is able to really fathom. This is the most exciting time to be alive, and it's just going to get more exciting as the months go by.
