Regardless of what any armchair economist thinks about the federal reserve, how can you love bitcoin as a currency if you think that the fed 'plays an important function'?
I think the Fed plays an important function, but I also think that paper money won out over gold only because it was much easier to spend and verify. Otherwise, gold's track record as a store of value is clearly better. I think Bitcoin could outcompete the dollar, and if it does, central banking will end regardless of how I feel about it.
