There are very good reason for naming functions (and ideally dangling them from the class rather than making them inner functions) - this encourages you to separate the 'what' from the 'how' and tends to result in code that is self-documenting. When you inline all your functions the person reading the code is forced to build and maintain multiple abstractions at one time to follow execution flow. Additionally, you are conflating the 'what' and the 'how' which forces the reader to context shift. If you replace the function with a well-thought-out name, code becomes much easier to read.
