I can think of many reasons to deliberately create software that is inefficient. Number one on the list is to make it more reliable. The number one reason software is rarely reliable is because code is more often than not complex to the point where the developer unsure whether it will work or not. In turn, this occurs most often when trying to maintain state via flags. If, instead of trying to maintain state, the software is designed so that the current state of objects is always a function of the original state of the object at the time the App started, you have an App that is potentially slow but like to be extremely reliable and extremely easy to read. I always program this way these days and my Apps are always reliable. For example ToteRaider (see Toteraider.com), a complex gambling App, released 2.5 years ago is still on version 1. Zero defects in production and also zero defects in testing.
