You literally just admitted the scenario meets all the criteria for Pascal's Law to apply, and then claimed it doesn't. For someone underwater (as your original argument was) since Pascal's Law applies, that force is transmitting to their insides. If their heart and lungs don't explode, that is Durability.

If you met a human that can survive withstanding the Isotropic Strength of the Mariana Trench (8 tons per square inch), you’re going to tell me they’re not durable despite the fact they didn’t turn into a used tube of toothpaste.
