Catalonia has nothing to gain from this struggle. Spain will not give-in to their demands because they already know what happens when you do, their demands only increase. It happened in Honk Kong and now China regrets it deeply. Those 12 steps or Rules for Radicals are becoming outdated and only increasing centralized government expertise into dealing with radicals. I believe Spain will never concede one inch to separatists even though their cause is noble and seem to be just. It just goes against the plans of bureaucrats to start balkanization of nations that soon. Maybe later once dissolution is economically interesting for the whole EU block.
