The irony is that replacing a perfectly functional plastic coffee maker with a brand new $500 stainless steel one might be worse environmentally than just continuing to use what you have
Not really, you'd be better off health-wise with the stainless steel one. And, the plastic coffee maker was already bad for the environment the moment it was manufactured; whether it is actually used or not is irrelevant.
