And (as I often argue here[1]) that's still a mispurposed argument when used against plea bargaining per se, rather than against the forces that give prosecutors so much disproportionate leverage that people take them.

It's not even a case where removing an option can have good global effects; if you remove plea bargaining but change nothing else, all that accomplishes is that disadvantaged people get railroaded harder, and choke up the courts even longer as they play out their lopsided trials.
