Infinite chakra does not mean larger chakra capacity. Living forms have larger capacities than their edo forms, although edo's have infinite replenishments. Breaking Edo Control was not about power, it was about Madara knowing how to, he knew the hand seals and the moment he was able to use it so he did it. Itachi said already he never wanted to kill Kabuto, only release Edo Tensei and "heal" Kabuto from his hurt and misguided mindset, hence he used Izanami on him.
