I dont entirely disagree with the principle, but, at the same time, will you spray water on the ground you walk on?

I don't have a lot of concern for what I walk on. It can be raked or swept, watered if needed on concrete if it's a concern. On grass or soil it just creates more favorable soil. I take my shoes off at the door, so I don't see any issues.
