Questions/Discussion
Being super-literal isn't the right approach for everyone, but for some people (like me) it helps bridge the gap between "it feels like there's a lot of smaller parts and I don't understand how they work together" and "I intrinsically understand this."
So for me, struggling to come to terms with this, this grammar construct feels like "to not do _verb_ is undesirable / not good." The negative form of the verb, and then ては marking the action, which is followed by ならない (should not come to be) or いけない (prohibited, bad).
Hence, "to not _verb_ is an undesirable outcome / bad" => "must do verb," in a roundabout way.
This also makes sense with the less-severe ければ form, given that ければ means "if." The potentiality of the "if" lessens the strength of the "must," I guess.
Edit: Just noticed that マイコー did say something like this 6 years ago in the archived comments, lol, sorry. I'll leave this up anyway, in case it helps anyone else.
