Rashi on Vayedaber Elokim might shed some light.
Also, the list of Brachos are not related to the list of Klallos, while the obvious opposite of ‘you will live long if you do this’ is that otherwise you won’t. Rashi is saying that the Torah uses this as a means to convey a message.
Lastly and mainly, I agree with Daas Yochid that not everything in the Torah is a Tnai. Nobody thought to bring up ???? ???? when you don’t transgress a Lav to keep you from getting Malkos. In the Torah Hashem is letting you know what the benefit is, or the punishment. ?? ?????? is actually being expressed as a conditional arrangement .
