Because the process of teleportation involves the energization and subsequent materialization of the teleportee's body.
It calculates based on the essence of the teleportee, rather than superficial changes.
Insufficient teleportation energy can result in serious consequences.
At best, the teleportation fails; at worst, it tears the teleportee apart, with parts on either side.
Gaven learned this lesson the hard way.
Previously, he attempted to teleport Treants by reducing their size as a trick.
Fortunately, since those Treants were Awakened Plants, the incomplete teleportation only caused them significant life damage but wasn't fatal. They could recover with some rest.
Since then, Gaven played it safe, never daring to be clever or use tricks in magic.
Because these methods cannot make up for the deficiency in magic power, ultimately resulting in self-defeat.

Bargaining is an instinct deeply ingrained in merchants.
