How could you go lie in wait to ambush someone (1:11) or go to the house of the harlot (5:8) unless you physically walked on a path to go meet up with them. You had to physically get up, go outside, and walk to the door of the harlot's house. There was actually effort involved in entering the path of the wicked.
We need Solomon's words even more today. What do I mean? I mean it is all too easy, convenient, and anonymous to enter the wicked path today. Now, every IP address is a path to folly and every sort of evil. A step only takes the press of a button, a single click of a mouse. The path of the wicked is all around us, floating in the cloud, choking and blurring our way.
