As a European, it seems reasonable to me. I think the UK should let one or two generations pass to assess its true power, influence, and wealth in the world before making any major decisions. Similarly, the EU needs to find its own way, see how far it can go without the UK (and possibly without the tutelage of the USA), and thus determine what concessions it might need to make to the UK in a negotiation and what aspects would be non-negotiable.
