You wouldn't care.

Sajora, Forever of the Dawnto Runewarden Serethipas

When you ghost on every hit and wait for somone to bail you out I can see why any sort of herb wouldn't concern you but those who actually stick around to you know fight each abstract concept to you I'm sure may enjoy having herbs and poisons. Perhaps why they are being overcharged is due to the rarity and the effort in obtaining it in other ways. If there were a shortage of teleport items though I could see you kicking up a fuss.
