1)Hody is a fishman who is designed to live and breath 10k meters under the water. He was born on Fishman Island, chances are he can take the pressure.

2)Luffy is in an air bubble that has been shown to be practically invincible, so he is protected from pressure anyways. (I think)

3) Luffy is made out of rubber, so he wouldnt feel the pressure anyways.
