The examples you're listing aren't just words. They're actions.
I could say I'm going to deny your health insurance, or deny entry of your type to my group, or sue you for something. But notice how me saying any of these things don't actually have any immediate effect on you, because I don't control your health insurance or moderate a group you want to be in, or know who you are to sue you.
I can use words to convince people who do control those things to do things to you, but you can convince them not to, and convince others to do the same thing to me. The value of free speech is in replacing these conflicts that would otherwise be physical violence with words. Human nature didn't change. We still fight all the time, but with words.
They're words with consequences, backed by law and the freedom of companies doing all they're permitted to do; but fundamentally just words. Contracts are just words, but words with meaning and power, because we all agree to play by those rules.
