Why do you assume the government can’t plan out new property to replace the old?
There is no reason why they have to wait until the last day of the 99-year lease. There has already been talk of redevelopment of land prior to that.
The point is the government has made it clear - there will be no widespread lease extensions nor en bloc development. Most will simply expire.
I'm not - but this was 191 units. What happens when 20,000 units expire in a single year? You have a lot more confidence in government than I do. Besides, your top level comment was about how western countries could resolve their housing crisis with the SG model. My contention is that the SG model as it exists could only work in SG - if it does at all - which still remains to be proven in the coming decades.
