I dunno, maybe. I think limited liability is a good idea for investments, regardless of the form which those investments take. It seems reasonable to create a dynamic in which nobody can lose more than they put up. If you go beyond that, it's going to severely hamper investment.
The older I get, and the more I watch the world change... the more I think that the problem isn't limited liability, it's the stock market. It's the process of turning shares into commoditized items to be traded without a real connection to the underlying value and expected outcomes of the company on which the shares are based.
It would complicate a lot of stuff... but if shares could only be purchased directly from the company, and not traded in a secondary market, I think a lot of problems would be mitigated.
