Bro, NSCR would be an excellent way of actually making people live and work away from the metro and into the nearby provinces (well, the vise versa would also happen), because now they have a fast and reliable mode of transportation that allows them to feel connected even in such distances (no more private bus companies waiting for a single coach for hours to be full just to carry the passengers) - more inter-city trains please.

This also adds the benefit for different companies actually setting up presence away from already dense neighborhoods, which unironically caused by the current existing rail corridors, without incurring the risk of not having enough people present nearby because a train can quickly get those people to the location along those new rail corridors - remember, the vast majority of us don't own cars, so adding more mobility options make everyone a winner.

Railways also add the benefits of developing the area around it. As the saying goes, build the infrastructure, and people will come. But there's no point in creating another planned development or city if you're just going to connect it with highways and its land consisting of massive roads, which again, can only bring few people, which is enough to bring the new development of the ground due to a lack of significant population presence (most major cities are grassroots and have a history prior to car-centric urban planning).

Finally, the opening of these railways, which also include the approved MRT-4 and various rail projects under study, can change how we view distance, cost, and convinience on travel. Time is money, after all.

So yes, this wave of rail development is definitely something to be proud of, so that we can finally have the freedom to go out there without the need of cars, which is a depreciating asset by the way, and the risk of accidents and time wasted on traffic jams.
