They're describing a border. When I was a teen in the late 90s, the internet without borders was cool (until I wandered into trolls I didn't have the resilience to deal with), but very obviously not compatible with national sovereignty on what counted as "illegal".

Now? Does any country today block zero domains? There's nearly 200 nations so I've never bothered to check, but my guess is all block something.

Not just a border, a closed border. That's not common except in times of war or extreme authoritarianism.

Banning a company from doing business with a country is called "sanctions", not "war", and sanctions happen a lot.
