Grouping the nation's patients and livers into fewer, larger regions might allow broader allocation without the risksof having to fly organs across the country (even with the best care, livers can last only half a day on ice).
There are of course no guarantees on gains or preventing losses of your portfolio, but maintaining your preferred allocation can help spread the risksof your investments more in line with your risk tolerance and lower the levels of swings you might see in your account over time.
But free markets are inadequate or fail altogether in the allocationof public goods, in addressing systemic and catastrophic risks and economic externalities.
