What about:

Probably because the end result is more complex than a programming
language. Macros are created to solve a complex problem and tend to
deal with borderi cases as a side-effect. This makes their behaviour
incomprehensible. For a handful of those macros there's no problem,
because the abstraction is not getting in the way. But if everything
is to be expressed with macros, the expression power of the resulting
language is highly non-orthogonal and irregular and macros tend to
end up having weird dependencies among each other...
