Absurd. Water raises the boiling point of the fluid and its what actually carries heat from the engine. Antifreeze to put it simply just keeps the fluid from freezing.
If you live in a hot,year round climate I would use mainly water at an 80/20 mix ratio. If you experience winter or sub-zero temp at some point during the year then 50/50.
Your engine guy may be a great builder,but to even suggest not adding water 0,without some form of alternative is not very good advice. I don't suggest taking his oil advice either.
