Once I realized my introversion was psychological and mutable, not some fixed aspect of my personality, it changed my life.

We tend to anchor ourselves to labels. Lots of introverts I meet limit themselves in life needlessly because "I'm an introvert!" I see my old self in them.

Good on you. But this doesn’t apply to everyone. Hell, I’d even be willing to bet that your case is extremely niche.

Introversion can be a byproduct of so many different things that saying “it’s just a label” is not only absurd by itself, but utterly disrespectful too. It can be a choice too, sure, but that’s not the case for quite a lot of people.
