Where, wherein and in which are completely interchangeable?

Hello,

Where, wherein and in which are completely interchangeable?

Example Sentences:

-That paternalism in domestic policy goes hand in hand with a mercantilistic view wherein the world economy is a group of mutually antagonistic trading blocs.

-The San Francisco house, wherein he and his family live, was damaged by the earthquake.

-Anyway, the woman character has something of a soliloquy on the verbs "pee" or "piss" wherein she asserts that the words are derived from the word "penis."

Outside of these examples, Where, wherein and in which would still be interchangeable?

Many thanks
