It's all a spectrum, the question is whether a better system is conceivable or achievable. Scotland was offered a free vote on leaving the UK and voted to remain, if they'd left I wouldn't have wanted us to try and block their entry to the EU or otherwise impose tarrifs or create ill will. You could argue that they should schedule a vote once a decade, I don't think I'd oppose that. If they wanted another vote now that also seems fair.
