Protein needs vary by body size, age, activity, and goals, which is why one generic internet number often creates more confusion than clarity.
Why context matters
A sedentary adult, an older adult trying to preserve muscle, and a strength-training athlete are not dealing with the same practical protein question.
Bottom line
The useful question is not “what is the one true protein number,” but “what level supports my health, satiety, and activity level realistically?”
