I think whether houses should be sold on a 99 year lease vs property is a large and separate question. The vast misunderstanding of it still remains - the idea that a house is owned, not rented. Selective properties might be bought back. But the fundamental invariant of this whole situation is that all 99 year leases will worth 0 eventually. Any rise in prices now only increases the eventual depreciation. And add on that massive loans are taken out on depreciating assets, so it's not an investment, it's a liability. And the significant majority of Singaporeans bears this liability on their books.

That's not how it works. The flats aren't valued for their space in the sky; they are valued for the land they are attached to, and their proximity and connections to other communities and infrastructure. I've already said that flats slated for SERS are bought back by the government at market rates well in advance of their leases expiring.

What you seem to greatly misunderstand is that land in Singapore is at an extreme premium, the likes of which is hitherto unseen anywhere else. With this context in hand, the idea of traditional 'home ownership' is fundamentally flawed in the first place, because unlike much larger countries, there isn't a large suburban or rural zone in which a new city can just be sprouted up. 750 square kilometres is all you have, and if you have to recycle existing land to maximise its use, so be it, and if it means 99-year leases, then that is the cost.

Given average human lifespans, the Western concept of a 'freehold' doesn't really make that much sense anyway, unless you want monarchies, oligarchies, or corporate dynasties monopolising prime land and settling into an even more predatory outright rental economy, which is already seen in most large cities elsewhere.
