I live at 68*N. I think I know about frozen ground. When it's frozen here it's covered in ice and pegs are useless no matter what they are made from. So I tie off on trees, bushes, saplings, stones whatever is at hand. I have never needed pegs to get a tarp up.
As for rocky ground. If the ground is rocky there are stones. Also in snow you don't use it as a stake, that you drive into the ground. I just lay it flat on the ground and cover it with snow. That will hold it plenty good enough if you use a meter or more length of it. I used it in Blizzard conditions and gale force winds last weekend. Held nicely.
