Who told you that you need that much protein? The amount you're talking about is the one commonly used by body builders who are using steroids. That's an absurdly high protein intake for a normal person.
"Thus, 0.75 g/kg per day (0.6 × 1.25) is the recommended allowance of reference protein for young male adults." [1]
Bodybuilders often do 2x their bodyweight, and more when counting the amount of grams to intake.

Sorry what? Those of us who lift and are trying to grow muscle take more protein, but don't just lump us in with steroid users. https://examine.com/nutrition/how-much-protein-do-you-need/ is an evidence based review on the subject.
I lift and I've found the 1g per lb to be excessive. My point about steroid users is that that's what they eat too.
