Why?

scratches = rust

Kinda defeats the purpose of coating the cast iron.

1. Isn't cast iron much harder than aluminum?

Than anodized aluminum? Aluminum is certainly harder than Boeshield.

So is wood. So is plastic. So is my fingernail.

I doubt you'll scrape off the Boeshield with your fingernail but I try
not to drag my fingernails across the top, too. Nah, wood and plastic
might push it around some but it's not going to plow through it.

2. How is one smoothly polished, soft metal going to scratch anything
let alone a much harder metal?

It does. My aluminum miter gauge certainly scratches the top.

I think you need to be a little more gentle. :-p

I guess I could put UHMW strips on the bottom but really, the miter
gauges do scratch the surface, in multiple places.

If yu are using Boeshield to protect your TS top you don't have near the
rust problem you might think you have.
Boeshield absolutely would did not offer enough protection for me when I
first used it 15 years ago. TopKote and its successor is the only thing
that works for me.
