I don't think RDAs are "minimum recommendations" but rather what's considered healthy (1) Also, from the report you linked, the conclusion seems to be "efforts should be undertaken to ensure that Americans consume the recommended amount of protein" and that "The percentage of the male population who consumed less than the estimated average requirement was very low". So, I'm not sure how you're getting to the conclusion that we ought to be eating more.
