I haven't seen any studies that guarantee the safety of wearing cotton clothing or rubber shoes, both of which have vague effects on electromagnetism as well. Not having any evidence that it's unsafe is good enough in my book. We've had a couple of decades and millions of flights where passengers forgot/ignored/didn't understand the rules without causing a single incident.
