Here's a rundown of the first "random" passage he quotes from Maps and Meaning (random my ass): Peterson is trying to connect moral system to conflict. He points out that repeated heroic (good) action can't create a unifying moral code for the whole world to live under because it's essentially always a negotiation between competing moral systems/civilizations, each with their own description of what a heroic action might be in a given situation. This conflict often results in wars which can upend/destroy certain systems or combine them together. He further describes the psychological working of moral codes, in that they need to allow the present reactions to be justified and rationalized by the possible future repercussions rather than letting only the present consequences decide the value. And even if you have your own desires and moral code in place, you still need to be able to continually reorganize it due to the need to interact with others who have a different system or an evolving system.
Now, this is my summary of that paragraph with having literally no knowledge about what chapter it's from, the surrounding meaning, the surrounding context. If I had those as well I could give an even clearer interpretation of what the overall point is - here he seems to be mostly wanting to describe the function of moral system on a personal, communal and global scale in relation to conflict.
His second passage is about how law is mostly a positive influence but that you shouldn't be an absolutist. It's pretty damn straightforward.
Those are literally the only two quotes pulled from the book. Are these passages meaningful? Well, they are descriptive, and he's mostly spending time outlining the edges of ideas he uses later. The passages make sense. They play into larger claims. Not sure how much more meaning you need from random paragraphs pulled out from a 600 page philosophy text.
No, I said it was unfair to pull
so little out of a 600 page book thinking that's going to count as a legitimate critique (i.e. cherry picking). I would claim as much for any attempted criticism of any other philosophy book using this garbage 2-paragraph-whine-session method of argumentation.
I don't know either, because this critic has blurred all his criticism into one messy conglomeration pulling various quotes out from decades of material. For this point in particular let's assume the context is M&M - I found many of the ideas there not banal. As I've said I found many of his connections between ancient myths and evolutionary psychology something I've never heard before. Not sure what else I would have to say to refute this "banal" claim. Here is one of his lectures that truly fascinated me with the connections he made:

For that particular passage "intrapsychic spirits" - intrapsychic just means internal thought. Spirits can be considered a synonym for the "decider" in your brain - also referencing the use of "spirit" as something untamed or wild, that is controlled through things like law. It's a way of characterizing a person's choices (he calls this "potentialities"), and in this context how the law helps directing a person's "potentialities" (decisions).
"allows spiritual water controlled flow into the valley of the shadow of death" i.e. law allows creative/courageous action (directly referenced in the same sentence, described now as "spiritual water" for beauty's sake) to take place within a chaotic world (valley of the shadow of death is an Old Testament phrase referencing the chaos/suffering of life). Again this is my understanding of a paragraph pulled from a 600 page philosophy book. With more context I could give a fuller explanation.
You're exactly right - it isn't a book report. It's completely ineffectual as a criticism against Peterson's philosophical work on myth and evolutionary psychology because it's literally just two pulled paragraphs.
Here is a breakdown by a lawyer of the problems with the bill that Peterson was protesting and how it could result in legal consequences:
