Whether something is "economical" or not is relative to the
preferences of the decision-maker. And the preferences of a single
person like ourselves can effectively be a weighted average of many
different preferences, as if we were composed of parts with many
different preferences.

So to make your scenario plausible, you need a plausible process which
creates this massive convergence to a preference with almost no weight
on long-time-scale returns. One way to get convergence of preferences
is via evolutionary selection, but that process seems to select
exactly for the preferences you don't want in your scenario.
