That said, the DAO didn't control the core contract. So to the extend that the core contract was used *without* any of the ancillary tools (website, DAO controlled smart contracts) then you COULD still maintain you had no control over that activity.

So then the defense in the US would have to fall back on the non-custodial side of things. At minimum they didn't need a license.
