I might be wrong but it doesn't sound like you've really read his material beyond 12 Rules for Life. It doesn't necessitate believing in something that does not exist but it will at least leave you with a deep respect for your subconscious and for the collective subconscious. That's enough to understand the value of religious stories. Once you're there, belief in God is your own business... it's not even clear if he believes in God and I'd say it's barely relevant.

You might try reading the book Sapiens by Noah Yuval Harari. Among other things, it shows how intersubjective realities such as human rights, religion, and money make civilization work, whether or not the objects of those stories 'exist'.

I don't think you have to fully understand or agree with him. In large, I don't. Your paragraph, though, is a gross deliberate misunderstanding of his view. :(

Again, I don't necessarily agree. In large, I think he is familiar with a different nihilism than I am. I grant, however, that he probably knows the topics better than I. I certainly plan to dive deeper on it. In large because I disagree.
