You must have very soft facial hair, not be prone to ingrown hairs, be okay with a lot of tugging and uncomfortable shaves, or produce a ton of oil. Even using feather blades on a DE safety razor, I have to replace the blades at least once a week. With no shaving soap I get tons of irritation despite using witch-hazel afterwards.
Next you'll be telling us that cold-water shaving is THE BEST THING EVER! 
Shaving foam is a total con.
Shaving foam? Maybe. You can use a shaving soap. Some people like the pre-shave/shaving oils as well as lather-less creams.
