Why Should Bitcoin be Valuable?

Responding to a real life question, why should Bitcoin be valuable at all? Doesn't it "not do anything?" Here I discuss the ramifications of a digitally-based world financial system and what it means for bitcoin price. Bitcoin can not only be used as a store of value to replace gold, but can be used to write higher-level applications on it to make trustless and peer-to-peer financial derivatives, which could soak up obscene amounts of the financial soystem. The market cap of Bitcoin has astronomical potential, and owning bitcoin means having a permanent share of this system on the ground level.
