I assume that, whatever his views on the EU, aken won't be voting against independence in a second referendum, and nor will other independence minded voters.

As I pointed out many people excluded from voting on the EU will be able to vote in such a referendum, most of whom are likely to vote for staying in the EU. And even if the economic experts do warn that breaking up the UK might be bad for Scotland, the EU referendum suggests that what the economic experts say doesn't necessarily count for too much with angry voters.. A lot of Scots will be indignant at having their choice overuled - and it was a far higher proportion voted to stay in Scotland than voted to go in England.
