Freedom of speech is the concept, and 1st amendment is an implementation. The maximal possible implementation given the rest of constitution that came before it. So it's not just government in principle, only in practice.

At best, it's against government intervention and in public spaces.

If you come to my house and start shouting nonsense you will be very unceremoniously and quite authoritarianly be kicked out and not much anyone can do about that :-)

It's a fun metaphor but there are so many ways in which it does not apply to the topic at hand. This isn't about an individuals autonomy on their own property, it's more about a societal contract and expectations over civil liberties / human rights. Comparing it to kicking people out of your house is not even on the same level.

I like to say that the Eight Amendment prohibiting cruel and unusual punishment likewise only applies to the government.
