The restricted set of available investments will become overvalued, and the return on them greatly reduced.

SS is not fatally flawed "because it did not adequately anticipate future rates of inflation or life expectancy." Its fatal flaw is its coerciveness. If one could freely buy and sell claims on future SS benefits, I assure you that the market mechanism would reduce participation and the price of the claim, thus raising SS returns to something reasonable.
