""Why did anyone ever do so in the first place?" might be closer."
I'm interpreting this as "why would we need lawyers, we did fine without them", but that is very untrue. In the past there simply was much less rule of law, with the cronyism and systemic state of fear of citizens that follows from it; as is still the case in most of the Third World and especially in places like China and Russia. But to a lesser degree also in Westerns countries in Europe and the US, and especially in places and/or social strata that don't trust the legal system, or where those who are supposed to uphold the law are corrupt.
Lawyers may seem to be a net tax on the system, and the rule of law could theoretically exist without lawyers, true; but history has proven that systems where people have access to specialists who can fight for their rights are more efficient and, more importantly, better to live in than others.
