I think you're wrong.
I have to agree with the others here. Elizabeth sounds like a great person and she will get a load of stuff done, she's obviously very organised, passionate and motivated about trying to make Bitcoin work, but I just don't see her as contributing much to the board in terms of experience or opinions (no offence, Elizabeth!). I think she would be better served as a representative of the BCF in Washington, or a voice for Bitcoin in the press/media, or someone you know you can depend on to get things done or form order out of chaos.
I think having someone with more experience of Bitcoin on the board is the way to go - Trace and Joerg would be better in this perspective. I personally am tending towards Trace, because I think right now the time is right to engage with governments and banking industry rather than try and convince them by edging slowly towards the cryptocurrency singularity - I have tremendous respect for Joerg but some of the seemingly confrontational things he's been saying in interviews really worry me.
Just my 2bitcents
