That's a tautology... But, maybe if I try to salvage what you were trying to say: while failures are a fact of life, higher-quality products will try to minimize and mitigate more of them. Making more components replaceable, is the direction to improve resiliency, and therefore quality of the system. It could be impossible or highly impractical to make everything socket-mounted, but making more components socket-mounted is certainly a way to make a better product.
