I thought of consumerism because I don't see perfection as necessarily implying materialism. When I think about materialism, I think of someone who likes to show off their flashy car -- this is about having something expensive, a little bit opulent and excessive. Like how people buy expensive SUVs that are perfectly optimized for off-road driving, but they use it to drive to the mall and back. That's just stupid.

Something that's over-engineered is not perfect, even though it might be "the best" in the totally abstract sense, removed from any real-world implications, of having the best specifications. For most people, the perfect car is probably a Camry -- or something else ordinary and ubiquitous, not a status symbol at all, but perfect for solving their problem.
