You didn't actually answer my question. How does using the word for people who want to create a Jewish state make sense when a Jewish state has existed for 78 years?

One reasonable possibility is they're referring to people like Ben-Gvir who have themselves claimed that Zionism means fighting for Israeli control over more territory like the West Bank. They're the ones calling the shots right now. I don't know whether Zionists 78 years ago would've agreed, it's possible.

To some it still means favoring any existence of a Jewish state. The inertia isn't there because aside from the original partition plan being pushed by the UK, other countries have attacked Israel several times later in ways they would've have withstood without outside support.
