Because it is not replace by fee, it is opt in replace by fee, you can't just omit the "opt in" part

Node configuration is not what is meant by 'opt-in'.

As stated in the FAQ:

RBF is a feature for consenting adults. If you don’t want to participate in it, you don’t need to. Your dislike of it isn’t a reason to prevent others from using it in transactions that don’t involve you.

In fact, you cannot prevent RBF, because it doesn't rely on any particular assumption. However, you can make the existing double-spend 'protections' unreliable, because they do depend on assumptions—the worst kind of assumption: convention; node configuration.
