I think by "feasible", the author here means "the features required to support monads in rust could feasibly be added" not "it is feasible to implement monads is rust as it exists currently".

That was my first reading, your reading didn't occur to me, so I don't see that the title is especially misleading.

Support for monads in Rust is not possible to be added easily to the language, nor is it particularly probable. The features that come with the imagined syntax in the blog post are non-trivial additions to the type system.
