Because a lot of us dream of a decentralized, digital world currency enabling frictionless global trade, and we are willing to sacrifice exposure to volatility to achieve that goal. And a lot of us have very specific attitudes toward the role of government in peaceful, non-exploitative trade, and see Bitcoin as a possible solution to what we see as constant governmental overreach. In short, we're idealists. We've been at the forefront of many revolutionary technologies (Internet, 3d printing, etc.).
