A Fanciful Idea

This reads like nonsense:
According to several reports in the Arabic media, prominent Muslim clerics have begun to call for the demolition of Egypt's Great Pyramids--or, in the words of Saudi Sheikh Ali bin Said al-Rabi'i, those "symbols of paganism," which Egypt's Salafi party has long planned to cover with wax. Most recently, Bahrain's "Sheikh of Sunni Sheikhs" and President of National Unity, Abd al-Latif al-Mahmoud, called on Egypt's new president, Muhammad Morsi, to "destroy the Pyramids and accomplish what the Sahabi Amr bin al-As could not." 
This is a reference to the Muslim Prophet Muhammad's companion, Amr bin al-As and his Arabian tribesmen, who invaded and conquered Egypt circa 641. Under al-As and subsequent Muslim rule, many Egyptian antiquities were destroyed as relics of infidelity. While most Western academics argue otherwise, according to early Muslim writers, the great Library of Alexandria itself--deemed a repository of pagan knowledge contradicting the Koran--was destroyed under bin al-As's reign and in compliance with Caliph Omar's command. 
However, while book-burning was an easy activity in the 7th century, destroying the mountain-like pyramids and their guardian Sphinx was not--even if Egypt's Medieval Mamluk rulers "de-nosed" the latter during target practice (though popular legend still attributes it to a Westerner, Napoleon). 
Now, however, as Bahrain's "Sheikh of Sheikhs" observes, and thanks to modern technology, the pyramids can be destroyed. The only question left is whether the Muslim Brotherhood president of Egypt is "pious" enough--if he is willing to complete the Islamization process that started under the hands of Egypt's first Islamic conqueror.
The existence of cultural treasures and heritage, as represented by the pyramids of Egypt, has nothing to do with being pious. The pragmatic view is this--destroying the pyramids would trigger revulsion and destroy the basis of pride for many Egyptians. 

It would be a costly and remarkably stupid thing to do, and assuming that the Egyptians would have the money and inclination to do something like this is the height of Western arrogance. It is the very definition of saying that the ignorant have no right to their own history and archeology. You simply have to trust that there is still some remnant of cultural pride that will allow the Egyptians to maintain their pride in what was left to them by the ancients.

Egypt is broke; what precious little money comes into the country is related to tourism. In other words, this is not going to happen.
