I feel like this will have zero protection against

if (result.isSuccess()) {
    handle_error(result.error);
} else {
    do_something(result.value);
}

Besides, this is exactly what the comment said about having to constantly check for return values at call site. I think this may be mitigated by some clever macro-magic, but that will become a mess fast.

Zero protections against what? Against the programmer telling the program to do something it shouldn't? Not programming language does that. If you resort to this sort of convoluted reasoning, the same hypothetical programmer can also swallow all exceptions.

The main problem you're creating for yourself is that you've been given an open-ended problem but instead prefer to not look for solutions.
