I'm a big fan of the Institute for Justice, which fights the good fight on issues like economic liberty and eminent domain.  Today they're launching what may be their biggest case ever:  a fight to allow compensation for bone marrow donors.

For reasons that aren't entirely clear, the 1984 National Organ Transplant Act forbids people to sell their bone marrow, as well as their kidneys, lungs, and so forth.  By which I don't mean that the ban is merely stupid; I mean there's apparently some reason to believe that Congress simply did this as a mistake, adding bone marrow into the bill at the last moment without really thinking things through.
