Overcrowding in Singapore?

I came across this well-written piece on the SDP website: http://yoursdp.org/index.php/news/singapore/4086-65-million-part-1.

It highlights the perils of pushing Singapore's population to 6.5 million. Indeed, I can't imagine sharing tiny Singapore with so many people.  As it is, Singapore already feels super-crowded. Trains, malls, roads...everywhere seems to be infested with people.  Oh yes, the property market is incredibly high now too, no thanks to the surge in population in recent times.  I have been hunting for a flat since coming back from my studies but no luck so far. The COV these days always seem to be in excess of 100k. Including the 20% equity, I'll need to fork out close to 200k cash! Sigh, wonder when I will finally be able to find a roof over my head.

Anyway, back to the article. One of the readers, BryanT, argued that since Singapore is a city state it is more apt to make comparisons with other cities in the world. But is that really true? If I can't stand the crowd in Cairo, I can move to Giza. But where can I move to in Singapore? From Pasir Ris to Boon Lay?
