Well, technically you're simply using boost, on said hypothetical V8, to replace displacement of an even larger engine.
Boost is literally allowing the processing of air and fuel that would not be present via atmo alone. Making a 2.0L process the air/fuel of a 4.0L is no different than making a 4.0L process the air/fuel atmo would provide to a 8.0L engine.
So, the statement that "Yeah, well, I can boost the bigger engine and make even more power." In fact further verifies that boost is a functional replacement for added displacement.
