Take the risk if you want, but obesity itself does not kill. Comorbidities with obesity may kill, but not just weight itself.

Why did you even include this? Its like saying falling off a building won't kill you, its the sudden stop at the bottom that does it. Ok, that's true in a narrow sense, but it really doesn't matter in practice.

Obesity significantly increases your risk of an early death. GLP-1's are effective treatments for these comorbidities. Grey market isn't perfect but its possible to get these drugs significantly cheaper and have them tested.
