It's considered commercially necessary because reading through logs is not as effective as using a Web tool like Google Analytics for the task of understanding what users are doing on a website.

If you want to make the argument that there's no difference between using e.g. Unix tools on a log file and using a tool like Google Analytics, that's your prerogative. But the industry as a whole disagrees.
