Even though I think most current use cases besides payments are regarded, I do encourage anyone to build whatever they want in whatever way they can. 

Nowadays we can do things on the internet that we couldn't imagine 25 years ago. That's because people tried building stuff instead of just making email better and faster. I hope in 25 years from now we can do things with bitcoin that we cannot imagine right now. 

Let builders build and the market will decide what will be used or not.
