No.
Let me start with Gordon's post again, less glib this time.
Gordon, given you label this as a disaster, does it give you any concern on what an iScotland might have to go through in order to continue trading with UK?
How can it at this stage - it would be a separate negotiation involving very different circumstances; for instance, an independent Scotland would have no land border with the EU, and any subsequent agreement an independent Scotland would seek to negotiate with the EU (pending applying for EU membership), such as custom union/single market, would probably not be identical to that just negotiated by the UK. Moreover, an independent Scotland's preferences as regards its immediate relationship the EU post independence would clearly be a factor in its negotiations with the UK.
The issue that the Guardian link highlights is that what has just been negotiated by the UK government is already proving to be problematic, and that is a consequence of the UKs particular approach to the EU, which may not be the approach adopted by an independent Scotland.
