Could this also be interpreted as a kind of rhetorical conditional, as if:
If I don't agree, there is no agreement or unless I agree, there is no agreement without my agreement, there is no agreement

Yes, I agree. DL does this a lot. Perhaps English is fussier than Hebrew in this regard (or perhaps it's just DL).
Yes yes yes! Good point! Run-on sentence. https://en.m.wikipedia.org/wiki/Sentence_clause_structure
