> From this you can derive conservation of momentum isn't just some empirical relation we have historically observed, but critically linked to symmetry of translation.

It changes conservation of momentum from an empirical relation we have historically observed to something that is derivable from a different empirical relation (translation symmetry) that we have historically observed. It's still ultimately an observed empirical relation.

It gives you something more to check. Your con-man adding n^3 terms to force equations saying this is the basis of their reaction-less drive is easy to dismiss, as even their whack-job theory implies conservation of momentum (and no reaction-less drive).
