Hyp, so how do you match the blink spell text with
Etherealness that states: "While on the Ethereal Plane, a creature is called ethereal. Unlike incorporeal creatures, ethereal creatures are not present on the Material Plane."
Ethereal = on another plane
Incorporeal = present on the Material plane, albiet without a body.
That paragraph contrasts a creature who is on the Ethereal Plane with an incorporeal creature who is not on the Ethereal Plane.
The state of being incorporeal does not by itself remove one from the Material Plane.
Consider - A creature who has yet to act in a round is flat-footed. Unlike a creature denied Dex bonus to AC, a flat-footed creature cannot make attacks of opportunity.
But there are cases when a creature who is denied Dex bonus to AC cannot make an AoO. What is implicit in the second sentence is a "merely". Unlike a creature
merely denied Dex bonus to AC, a flat-footed creature cannot make attacks of opportunity. This lets us know that being denied Dex bonus to AC does not
create the ability to make an AoO; rather, it tells us that being denied Dex bonus to AC does not remove an ability to make AoOs that already exists.
Similarly, "Unlike incorporeal creatures, ethereal creatures are not present on the Material Plane" doesn't tell us "incorporeality places you on the Material Plane"; rather, it tells us "incorporeality does not, by itself,
remove you from the Material Plane".
Let's say a spectre gets Plane Shifted to the Elemental Plane of Air. He is still incorporeal, but he is not present on the Material Plane. Incorporeality doesn't anchor him to the Material, but neither does it remove him from it. But if some other effect moves him to another plane, he will be incorporeal on that plane.
The Blink spell may make you incorporeal, but it also removes you from the Material Plane. Since you're not on the Material Plane, a Ghost Touch weapon on that plane will not affect you; similarly, a Ghost Touch weapon you take with you to the Ethereal Plane will not reach the Material.
