there are many excellent points made on this question but the standout one explaining the problem is >>When you're in a situation where mistakes can cost you millions, hiring an attorney for tailored advice is cheap insurance.

when you hire a corporate law firm you're paying for their liability insurance. Only products and services that can remove the fear if something goes wrong (i.e insurance) or what is the outcome does not stand up in law will really disrupt things. For the latter the government needs to be involved and this proposal in the UK will really shake things up for access to justice, costs etc if it goes ahead http://www.theguardian.com/law/2015/feb/16/online-court-prop...
