lol.  i think cerebral makes more sense as in "of the mind". 

lol. Well, he's arguing that bitcoins are tangible although they don't have a physical body. While I agree that being cerebral is not a prerequisite for tangibility, I think in this case he's arguing that being corporeal isn't a prerequisite for tangibility.

In case you think something that doesn't have a physical body cannot be tangible (which would explain why you think it should be "cerebral"), then you might want to listen again to the argument, because that's exactly the view he's trying to show to be inadequate in the case of Bitcoin.

Bitcoins are tangible

Yep. Corporeal.

It seems that the survey is public, so if someone wants to give his opinion on the matter:

I did fill out the survey. I suggested they talk to Trace Meyer and pointed them to his article about bitcoin tangibility: http://www.runtogold.com/2012/11/why-bitcoin-is-tangible-digging-into-the-guts-of-bitcoin/

This is very exciting and good news

you're coming around 

Well, $2,2B of bullion in the vault means that if .5% were allocated to bitcoins then it would amount to $11M. I wonder what $11M would do to the MtGox order book; particularly since prices are set at the margin.
