I didn't say encrpytion was bad But for an isolated use case where you control both ends and the network itself, it's entirely valid to say that it's overhead

I didn't say encrpytion was bad But for an isolated use case where you control both ends and the network itself, it's entirely valid to say that it's overhead with little benefit. Personally I think the benefits of using encrpytion by default outweigh the downsides, but I can see others may disagree, I wouldn't call them "flat out wrong".
