You are making an argument about internal struggles within a country. I honestly do not give one shit what you internally call your regions. But to the rest of the world they are not sovereign nations and are therefore not called countries. This would be like any politician in America arguing that California or Texas are countries because they’ve stated they want to split from the USA at numerous points. This is the same for Catalan or Galicia which have been trying for decades to split from Spain. Hell even Palestine is recognized as a sovereign nation by at least some other countries, this is not true for any of the regions of the UK.
