My understanding is that an NP is considered as autonomous as a physician. I know several of my friends who are PAs and they're lobbying to be treated the same as NPs, as they feel that some of their restrictions are unnecessary and bureaucratic, logistical issues only, rather than based on patient care.
I think you misunderstood the parent comment. The commenter is not saying NPs are a problem, they are pointing out that NPs aren't treated with due respect. The sarcastic use of "lowly NP" gives it away.
