An independent Catalunya would never be admitted to the EU - who would they trade with, Cuba?
It’s a disgrace that Spain has not been expelled or at least censured by the EU for their actions: assaulting voters, confiscating ballots, arresting political opponents. People should think very carefully before giving this a free pass just because they think that the people seeking sovereignty are “idiots”. Who knows when the state may think you’re an “idiot” for seeking some democratic goal.
