Useless Stamina Mechanic

I feel like the stamina is just useless.

It's not like we have thousands of tokens that we can just use anytime we want to exchange pokemon.

They could remove the stamina and the entire player experience for the mechanic for exchanging pokemon will stay the same. Am I wrong?
