Of course they can continue to use the euro. They wouldn't have any control over it, but a country can use whatever currency their population will accept. IIRC there are a few small nations that don't really have their own currency and just use USD instead.

You are right, I oversimplified it in my comment. People could still trade using euros. But I guess the only way to get more currency in the country would be via foreign trade. Banks would not have access to EU QE, deposit guarantees might be no longer valid and the state could no longer print currency to replace old ones.

Zimbawe did exactly that after their hyperinflation reached a point where they had to print 100 trillion Zimbabwean dollar banknotes.
