Whilst i agree, that modules/ships and equipment should wear over time, your brief summary is too general, and by no means am i an expert on the subject of entropy, but just because something is complex does not mean it will degrade faster then something of lesser complexity.
items/things in general can be designed to last. your example of the stone pillar surviving one thousand years and an F-16 only a few dozen hours, whilst possibly true, excludes many factors. ignoring the aspects of the pillar, and examining the F-16,we know it is a military aircraft, as such emphasis is placed on combat ability above all else, components can be designed to withstand stresses, but would detract from combat ability. from the design point, a real world example is combustion engines, in consumer vehicles such as cars an engine may only last a maximum of 800,000 Kilometers, which many would never reach before getting a new vehicle, in commercial vehicles an engine can easily pass 1,000,000 Kilometers, and do so potentially twice over.
I would add that modules/ships and equipment wear based on their design and quality, rather then a simple 'higher equals more'
