I've found that tracking tools are good to have even at times when I've been able to work in the manner of freedom the article describes. It's just that they are used differently, more in a way to help remember things. Things that either needs to be done or things that have been done. Especially those nightmarish things that took a long time to solve, so documenting the process is good for the future, in case it happens again.
It wasn't always like that for me (document, bah! comments, bah!) but as I grow older I've come to appreciate the possibility to offload information in my brain to a more persistent media. This way I only keep the index in my brain ("Hey, wait a minute, I recognize this..."). Maybe I'm just lazy but I hate doing the same thing twice. I also hate saying the same thing twice so before I explain something to someone I like to write it down and give them a copy. Then when they ask me about it I simply refer them to the document (in a friendly (RTFM) manner).
