We don’t have to justify using “similarity”, “resemblance”
I think you still do. In terms of induction, you still have the problem of grue and bleen. In terms of Occams Razor, it’s the problem of which language a description needs to be simple in.
Justifying that blue is an a-priori more likely concept than grue is part of the remaining problem of justifying Occam’s Razor. What we don’t have to justify is the wrong claim that science operates based on generalized observations of similarity.
