What initiated this discussion was someone saying no other system made sense, I explained why it does, the sense just isn't there in english.

Other languages have a distinct category for the ground level that separates it from the rest of the building and I’m saying I don’t think that’s necessary or very useful.

This is the monolingual part lol. Language isn't constructed around productivity or specific usecases.

but it’s not a deficiency of english that we wouldn’t say “a one story building doesn’t have any levels”.

This reads like you're going about me calling english silly.
