If there is a true "five nines" in our lives, it's the reliability of the law. We each interact with and under the law dozens, hundreds, even thousands of times every day without ever needing recourse to lawyers.
But when you need a lawyer, you need a lawyer. One might as well sigh heavily about needing plumbers when the pipe bursts. Specialisation is normal and -- this is what I like most -- lawyers are more than a paid service. They have a fiduciary duty, they are ethically required to be dutiful advocates.
Personally, while I wish the world was simple and lawyers were cheap, I have never regretted spending the money to consult with them.
Also hearing that I should take the same remedy whether I have a question or I need to be defended against criminal prosecution seems strange and intimidating, like being told I should hire a brain surgeon for a migraine headache.
It's irreducibly complex because it involves humans.
