I like const because I can look at a function signature and know that nothing downstream is mutating a parameter. I can also write a function that returns a const reference to a member and know that nobody in the future will ever break my invariants.

This isn't about "oops, I didn't mean to mutate that." This is about rapidly being able to reason about the correctness of some code that is leveraging const-qualified code.
