(Kidos can bypass it, sure, but it will be less effective). Therefore, in a fight between Shinigami, Ichibei would most likely win. Why would kidō be more effective than a Zanpakutō? You need to say "Hadō #4: Byakurai" to create a Byakurai, just as you need to say your release command and zanpakutō name to release a Shikai, for example, "Unare, Haineko".

My point is both kidō and zanpakutō have names... The big difference is that kidō isn't alive and everyone can do it.
