That is an extremely high recommendation. It's completely unnecessary. Dieticians, who are highly educated in this field, recommend a maximum of 1.7 grams/kg of bodyweight, and that is for high performance, elite athletes, who strength train. Olympic weightlifters, who have rigorous and frequent training sessions seldom achieve your proposed target of protein in their diets.
Far too many people over-emphasise protein in the diet. It's absolutely a necessary component of our diets, though consuming excess amounts of protein does not correlate with greater gains. You only need certain amounts, whereby excess amounts are chemically modified, usually as a fuel; though I can assure you, most people achieve their daily requirements without even knowing it; so consuming excessive amounts is unnecessary; particularly when you can divert your attention to carbohydrates instead - a far better, more efficient energy source.
