Mozzarella from coconut milk is the new thing /s

It has a similar consistency and it's uses are sometimes similar to butter in that it can be spread on a slice of bread.

It sounds like maybe you are aware of how silly your argument is now: the fact that these happen to arbitrarily share a common word in English, does not make them a substitute for each other. If you still don't understand, you should try sautéing some shallots in peanut butter.

Edit: this is clearly different from a company marketing a product alternative, such as margarine (for butter) or Impossible Burgers (for ground beef).
