No, of course not. Error handling is just one example. The monad interface makes handling that problem you mention---wiring errors through the value pipeline---much easier.

And the monad part is only just the "just" and "bind" functions. Everything else is about trying to make Python more explicit with its errors: "explicit it better than implicit", right?

Monads allow for easier composition of "values in context". That context might be error, or nondeterminism, or continuation, or state, or logging, or parsing, or parallelism, or simulation, or probability, or graphs, or prolog-like logic, or streaming, or many combinations over the previous.

And in every case, you have the same interface.
