What does this even mean: "declared independence"?

Have they ordered borders to be closed? Bank accounts to be frozen until new currency is introduced? Have people started throwing their Spanish passports and their euros into the trash?

It just sounds like a lot like pure political manoeuvre without any kind of practical consequence.

I think for them it's only about having their own constitution and sovereignty. Another one of their goals might be to stop using the Spanish language, which a big part of the population has done already.

They are perfectly fine with open borders, being a part of the European Union, using the Euro as currency, and even with keeping their Spanish passports (i.e. double nationality).

I'm sure they would, but once they are independent, they can't legally use the Euro. Would they even continue to be Spanish citizens and be able to travel freely in the Schengen area? A new state takes years to join the EU (assuming the EU would accept). How about sovereign debt?

All these (really important) issues that should be part of an extensive debate so that people could understand better what is expecting them on the other side.

Also, I don't know any country that allows constitutional changes to be done via a simple majority in parliament (they had 3 votes above simple majority).

The only reasonable exit at this point, I believe, is to have new elections.
