I think what he means is that, given the choice, people there would opt for a good class bungalow (essentially your 'detached home', but most will never be able to afford it).
That is an obvious statement, but the analogy breaks down a bit as in Singapore, whether you live in a GCB or in HDB (social housing), everything is relatively close by regardless. Hence, there isn't really much of a trade-off at all - living in a GCB just affords more space and privacy (at an exponentially inflated cost).
Good class bungalows are not your typical single family home. They are on huge lots even for a US single family home.
There are townhomes (shophouses), duplexes, single family homes as options as well.
“To qualify as a GCB, the property must have at least 1,400 square metres (approx. 15,070 sq. ft.) of land area, and the bungalow itself is limited to a maximum of two storeys in height”
People in HDBs want to live in condo, condos want to live in shophouses, shophouses want to live in detached freehold homes.
Everybody wants more space. And despite the great transit system, parts of Singapore can be more remote to the point a car being almost a requirement. And that’s what many people strive for.
