Is the NEXUS card proof of citizenship for purposes of applying for a new passport?
No. Foreign citizens can get a NEXUS card as well. See here:
Eligibility
U.S. citizens, U.S. lawful permanent residents, Canadian citizens, Canadian permanent residents, and Mexican nationals
You have to provide proof of citizenship to the Department's satisfaction (see the instructions to the form DS-11). The department will not be satisfied with the Nexus card since it is not on the list of the documents that would satisfy it, as you've noted.
Why can't you get your birth certificate? AFAIK you can get a certified copy from the county where you were born any time.

Answering my own question in a limited fashion based on experience:
I went to the US post office to complete my DS-11 application for a replacement passport card. I asked the postal clerk if the NEXUS card is acceptable proof of identity and citizenship for this purpose. She said, without hesitation, yes.
However, I did not truly test this, as I had in the interim found my birth certificate. I was not willing to mail my NEXUS card to the State Department, as it's the only border crossing ID in my possession and I will be crossing multiple times in the next few weeks, so I can't verify that the State Department itself would have agreed with the postal clerk's interpretation. Instead, I mailed the birth certificate.
