Dargah extremism in India

Why are some Indians so crazy about making and preservation of dargahs while the Saudi and Arabs mostly are of the view of demolishing it? I personally don't see any benefit in continuation of dargah business. It wastes space plus it has been explicitly prohibited by the Prophet pbuh.

Prohibition of Building Structures Over Graves: Several hadiths in Sahih Muslim and Sahih Bukhari report that Prophet Muhammad (pbuh) warned against erecting structures over graves, using plaster, or sitting on them, emphasizing simplicity in burial markers.

Warning Against Idolatry: The Prophet Muhammad (pbuh) is reported to have said that previous nations were cursed for turning the graves of their prophets into places of worship, cautioning his followers against similar practices (Sahih Bukhari, Sahih Muslim).
