User blog comment:LittlePeng9/FOOT is not as strong as I thought/@comment-5529393-20161225200516/@comment-1605058-20170125201718

I don't see why having fewer models is a better thing for interpreting a theory. If we want to interpret theory S in theory T, we need to (essentially) find a model of S in any model of T. If S is stronger, then it has fewer models, so it's harder to always find a model of S in any model of T.

What you are saying implies that if T is stronger, so has fewer models, then it's easier to interpret S in T. But we are discussing strengthening S, not T.
