For example, when Matt was at the bar as Daredevil looking for information no one had anything of value. The idea is that the Kingpin was so calculated about everything and hit Matt from every single angle imaginable. What is brilliant about the story is that over the course of the issues as Matt starts to rise from the ashes the Kingpin begins to become more and more unhinged.
As for Matt operating as if he isn't blind, I am not sure if it is ever specifically addressed (and if it has been someone please share); however, my theory, is that Miller wanted to breakdown Matt to the core of who he is and throw out everything that didn't work. You mention him going back to being a lawyer, I do know for a fact that Miller did not like the lawyer/vigilante concept, hence why he had him disbarred in Born Again. I am not sure if Matt not acting as if he is blind was part of that as well. The biggest irony of Born Again is that I think Miller's intention was to do a complete restart of the character (or provide a fitting ending to the character) where other writers could do new things and instead many writers have chosen to do their own version of Born Again in many instances.
Not sure if that answers all of your questions; however, I am definitely someone that believes BA is the greatest story in comics.
