actually there is no harm to have a bit of insurance just in case you dont die.If I can choose, I will rather have the old RSS.
Using the current CPF life payout amount, the old RSS is able to last until 95 years old.
Of course, RSS does not mean payout for life. However payout till 95 years old is good enough. And it will have even more bequest for nominee. Whatever interest generated is in the RA account. Straight forward and clean cut.
again it is good to take a look at what this insurance cost instead of using sweeping statement like everyone needs longevity insurance gates buffet mask pm lee all need it. you also need it.
200k frs at 55 = 300k at 65. lets say 50k go to pool. 4% * 50K = 2K/year. expensive or not? you decide.
