• Crime. Why do most people steal? Because they want something that they can't afford. What does Bitcoin do to costs? It makes things cheaper.
• It forces people to work and give effort if they want to make a living instead of living off of other people (Medicaid, food stamps, etc), thereby making society more productive and efficient overall.
• Reduces all forms of red tape by minimizing or eliminating government. Great for companies and great for people building for themselves.
• If a government exists at all, it makes that government more efficient because it actually has to provide services that people want for it to continue existing.
• It liberates those that would have been imprisoned otherwise for things that did not harm another person, their property, or their rights.
• It may increase charity as those who are most willing to give typically can afford to lose what they give.
• It rewards those that create and give real value instead of potentially being subsidized.

I could go on and on.
