Depends on where it is. In some places you need it, in some places you might as well do without.
Friction between parts you want to move is bad, it causes wear, generates heat and sucks up extra energy.
Friction between parts that you want to stay put is a good thing.
If you didn't have friction, pretty much everything would keep sliding around at the slightest chance. Open the door and the draught would have your furniture sailing across the floor.

∙ 12y agoIt is harmful and can be extremely painful. Your bones should never rub against each other. You have cartilage, tendons, and synovial joint capsules to protect, lubricate, and absorb shock on your joints. Together they help protect your bones and keep things working smoothly. They help keep motion smooth, reduce pain, and provide protection. If your bones rubbed against one another, there would eventually be wearing down and fractures due to the friction ,and left untreated, can cause serious problems. This even happens in the vertebrea.
