The why is important, I agree. For me, I had a hard time believing the "why" at all without understanding the "how." For instance, I could understand why a hard capped supply is important, or why no single entity should be able change Bitcoin. But without understanding how the network makes that happen, then I wouldn't believe that is even possible. So maybe it's just different for each person and how much trust you're ok with. I can't code, so it's not like I can audit the code and see what it's doing at that level. That's where trust comes in for me. But I can understand how the network operates and enforces rules, mines blocks, etc.
