Simply being out of the European political structure and bureaucracy is a good enough start in terms of what I was looking for. As you say, the further benefits will probably ebb and flow depending on how enthusiastic individual governments are about exploiting opportunities, but as far as I'm concerned, we're not 'European' and never have been. I have nothing against the ordinary people of European countries, but the European political 'project' isn't something we need to be part of.
