Effects can outlive the intentions that created them.

Things you set in motion keep running after your reason for starting them is gone. A rule made to solve one situation stays in the handbook for a decade. A habit adopted to survive a hard year keeps operating in a life that is no longer hard. Nothing in the world checks whether your intention still applies.

Look at something you do automatically and ask what problem it was originally solving. If that problem has passed, you are maintaining an answer to a question nobody is asking. Retiring it is allowed, and usually overdue.
