Actually, (b) is exactly the opposite. Instead of voting for certain economic policies and hoping "my guy wins" I can just use Bitcoin, which has the qualities I need, here and now: for instance, I can send money to anyone in the world without any of the KYC and AML bullshit and I don't need to wait and vote in just the right politician who promises(!) to easy the said regulations. I can certifiably tell you that I AM better off because I started using bitcoin. And it's not because of the exchange rate, but because of the freedom to do what I please with my money.
