In my experience, people usually try to avoid exchanging air with the outdoors when they're concerned about significantly heating/cooling their homes. If you're exchanging air then a heat pump could super heat/cool the outgoing air, and that's the piece I was missing from your proposal.

A pro with that solution is that the extracted air has a high temperature all year, making it more efficient that using a heat pump to extract heat from outside that might be -30 celcius. A downside is that the amount of air is limited, so if you need more heat then you have to supplement it with something else. You get it, but it seems there are a few others that don't realize that a heat pump can also be used to increase efficiency by reducing the heat lost. While I do get that it's unknown to most people, some people here perfectly illustrates the Dunning-Kruger effect...
