This is in line with what I've heard about sodium in the diet, which is that it's not bad in itself, but in proportion to your potassium intake.
I'd guess most Americans are deficient in magnesium and potassium, especially anyone who exercises regularly. If you're a male athlete, your actual magnesium need for example is about 800mg, which is twice the RDA of 400mg, which you're probably also not meeting.
I've helped people cure their chronic anxiety by noticing that they ran for an hour most days, and were taking zero supplemental magnesium.
