In a different perspective, the magnetic field itself is a result of special relativity. The magnetic field is an alternative way to explain electromagnetism without citing special relativity. (Or to say, electrostatic field and special relativity are sufficient to explain everything in electromagnetism, the existence of magnetic field is unnecessary.) If the existence of magnetic field is unnecessary, there is no reason to even search for a magnetic monopole.
