I was looking on Mises and was surprised that there is even a debate as to whether limited liability should be legal. Limited liability (ie. corporate personhood) is completely incompatible with libertarian philosophy IMO.
The idea that company's like Bain can buy a company, rip away and sell off all it's assets piece by piece, have the company take out loans in order and use that money to pay themselves and then bankrupt the company, rinse and repeat while taking no personal responsibility for the bankruptcies sounds like crony capitalism at it's finest.
Most of the problems associated with unlimited liability could easily be negated through liability insurance anyways.
