It's unintuitive because it's technically not true. All that suff about time horizon is right, but there's a legitimate reason that the fine print on the perspectus says you could lose your entire investment.
I’ll allow that I have the misguided presumption that I’d’ve been so smart as to have pulled my money out of the market just before Black Monday in 1929. But I still stand by the belief that the “gamble”, if following the Vanguard model of DCA and prudently managing risk over time to gradually shift from stocks to more stable “receptacles of wealth” whether bonds/gold/cash, is only a gamble that the United States (and thereby the world economy) will not utterly collapse on the scale of world war.
