The decentralized autonomous company has already been explored with things like Bitshares.  Frankly, it kinda sucks.  You have people providing decentralized funding, then the workers that take it have no real incentive or liability to perform unless the worker is already a huge shareholder...but that kind of extremely narrows down your field of workers doesn't it?  You could issue legal contracts with the workers and sue them if they don't perform, but who is the figurehead of the DAO that handles all these things and appears in court?  The DAO converges to centralization resembling a normal, publicly traded company because business is only efficient in a strict, hierarchical, top-down function.

So what exactly do you accomplish out of all this?  If the DAO doesn't collapse on the way to it's evolution in becoming top-down controlled, your only real benefit is the ability to bypass the legal framework and issue a publicly traded stock from your basement (which will probably get people arrested somehow).  So the pros are slightly less legal bureaucracy (only in the short term), with the cons of having nobody at the helm of the company who actually has any idea what they're doing with a valid business plan (you know, the actual important part of a business).
