Is this really an explanation of why manually iterating over a list is simpler than just calling a method?

Get is simpler precisely because it hides the complexity.

What makes those methods not subject to the "hiding complexity" objection?

It's an ill-considered stream of consciousness where I wasn't clearly separating "simplicity of interface" from "simplicity of implementation".

Part of what I was going for is that a clean interface might hide a complex implementation. If you've followed rule 1 and see that "Get" is a bottleneck, it makes sense to apply rules 3+4, and see if there isn't a simpler implementation than the one provided by "Get".
