Of course there is a way to broadly index among all non-negative seed investments: by broadly indexing among all seed investments.

The fraction of money-losing investments in a population will affect, for instance, whether we would expect the typical investor making five investments at random to make or lose money. But regardless of whether losers are 10%, 50%, or 90% of the investment pool, if the winners are drawing from an unbounded mean power law then broadly indexing raises an investor's expected return.
