I don't think there should be a republic of Yorkshire or Surrey either but there are millions who think that there may be a case for a Republic of Scotland, Wales, Ireland, (oops there already is!), whether they'd support such a split or not.  That is the point I was making when I posted that Scotland is not just a region of the UK but a country that is part of the UK.  

Equating Scotland with Yorkshire or Surrey is not a valid comparison.
