This song will not disprove the political reality that Bin Zayed will face in the future. And he knows it.
How about gathering the population like in a city (completely new city) which will be easy to monitor and control them? idk, like maybe in a unique city design, like a linear city, a single continuous structure few kms long and hundreds meters wide.
It will have its own unique governmental system, laws and even juridical system.
Most people talk about NEOM (which the 'Line' and 'Mukaab' are constructed ) as merely an economic diversification project to divest iSaudi Arabia from an oil-based economy. My argument is this is only explains half the picture.
The 'Line' and the 'Mukaab' are MBS's attempts to divert people from the very force within the Islamic world that stands in his way to eventually transform the Middle East to the tune of the Zionists.
The idea is to show Saudis the alternative, a godless Arabia with all partying (by Turki AlShikh), nightclubs, and liquor. In short an entirely new Arabia with an entirely new lifestyle that they hope would open the hearts and minds of Saudis to a new Westernized system, laws, and judicial system.
So even if the 'Line' and 'Mukaab' is a physical structure. the primary idea in constructing it is not to lock people physically but to lock them spiritually so as not to interfere in Bin Salman's increasingly secular policy and eventually their vision of a Middle East that tolerates the existence of israel.
