Earlier quoted context omitted.
What would be the practical purpose of "fixing" something like the pyramids? Vs. just preserving them as-is.
I think it would be cool to imagine ourselves as part of the process of civilization that created these buildings and restore them to their former glory. If the Mona Lisa was ripped in half we would surely restore it back to a single piece. Why should we not rebuild ancient Rome and host pop-up shops and events in the Forum?
And especially, over time, you can end up with a bit of a ship of theseus.
Also interesting -- if some day one of the earthquakes there knocks down part of the colosseum, will we rebuild the ruins to their ruinous state?
