Does anyone have a logical explanation for why the skin depth increases as the resistivity of the conductor material is increased? I know the equation, but for some reason, intuitively I think it should be the other way round? Correct me please...

An intuitive way to look at this is to imagine a material of infinite resistivity. Then the material is a perfect insulator which allows electromagnetic fields to penetrate without attenuation. Then there is no skin effect at all. Now imagine a perfect conductor, with resistivity zero. No fields at all can exist inside it. There the skin depth is zero. In between the skin depth varies, from unlimited to zero at the extremes, but always decreasing with decreasing resistivity.
