You're under representing the sadness of lost artistry. For example, there is a marked degradation in the quality of fine art between the late classical period and the early medieval period. Civilization in a large region of Europe lost skills for centuries.

We as a society don't want to lose artistry that was painstakingly developed - there's no guarantee it will ever be developed to that level of sophistication again. I don't want future generations to look at my generation as we do the dark ages.

I think it's easy right now to think that progress is guaranteed or the opposite - that it's impossible to achieve. As population levels out civilization will need to become more about archiving what we know than pushing the envelope but no one wants to lose information.
