Would life exist without friction? Not really. Everything would have to be held together by spring clamps--but then the dilemma arises on how to affix the spring clamps in their proper places. Sliding spring clamps would do no good at all. Would electromagnets solve the problem? No--because someone had to first install the hardware for that system to work. How do you attached electromagnets? With spring clamps? Screws and bolts are out of the question because they fully rely on friction. One possibility could be the use of the castle nut and cotter key (aka cotter pin). A bent steel cotter key in theory could hold; however, it wouldn't last long. The brunt of the weight/force is normally exerted on the castle nut. The cotter key is there only to prevent the castle nut from loosening. In a frictionless environment, all the weight/force would transfer from the nut to the key--because there is no such thing as a tight bolt or nut in a frictionless society.
Long story short: It's all about the coefficient.
Happy days, people!

I didn't follow a word of that.
