One could say that the "monoid axiom", which holds for chain complexes, guarantees that the monoids get a model category structure, but it doesn't mean that the category of monoids itself has to be a monoidal model category (for monoidal model categories, the tensor product of two cofibrant objects is cofibrant). | |
