Again, the problem comes in in the fundamentals of velocity of information propagation, of which only half is open to unrestricted scalability. Namely, documents can be propagated at the speed of light. Understanding cannot. You can put every document exactly where I need it as soon as it is accessible, but unless I've had enough immersion in the jargon and specific ways of life of the profession, I'm going to need time to absorb and reckon what to do with it, and where to go next. Even if I do know what to look for, good luck hitting up any database of well cross-referenced case law without paying an exorbitant fee due to the nature of the returns of the profession, and the essentially captive audience to it. Most of those data sources areas fundamental to law as Machinery's Handbook to Machining, yet its locked up behind more imposing barriers to entry than Fort Knox; fiscal, temporal, and cultural.

If it is too complicated for only professionals to understand then needs to be simplified. You are right we need fundamental simplication and radical change .
From the Justinian times codification and simplification of law has always been a mark of good civilizations. Asoka put stone pillars so people can know the law. There are countless examples. If ten commandments needed lawyers it would never have worked .
It will only happen if we doing something about it .
The de-facto necessities to succeed however, e.g., access to well-organized and consumable cross-referenced case law, the requisite knowledge of courtroom procedure, knowing what to file, by when, and what things mean without significant training or oversight of a retained lawyer; and that's where your issue comes in.
You could make the argument that an infinite number of courts and judges would bring the cost down; but I'm not convinced it would. As you'd still have the exponential case law parsing cost outpacing your availability of lawyers.
There comes a point where stare decisis and it's potential infinitive of cases depending on the craftyness of your lawyer at painting a distinction without a difference, and judges willing to buy it, where the costs seem pretty much guaranteed to spiral out of control.
