These "stress tests" are a little dumb, and nothing more than a propaganda stunt. We all know what the limits of bitcoin are, and the core devs definitely do.
It's like me putting a pot of water on the stove at 150C, and saying, "see, it boils! the stress test proved itself!".
It defeats the purpose. Those conducting these tests know exactly what the limits of the network are, so obviously if you push a test over those limits it's going to fail. Same as if I said I'm going to "stress test" aluminum, put it under a temperature of more than 660C, then day, "see, it failed the test!". Well, I knew from the onset it was going to fail that test.
You are right to some point, it
will fail, but it will also give some useful information. You see, even tho stress test seams useless, it does at least show :
-how much "damage" can only one entity/organisation do to the network
-it will show costs needed to do such a stunt
-you can use that data to understand what the next move in securing the network should be.
I'm not a fan of these "tests" either, especially when they come at a time of my weekly debit card top-up

, but bitcoin is at a point where it will be tested in many ways,
just for people to see it's capabilities, because it's not the question of what can bitcoin do and how it can preform now, it's about how it will preform when it starts doing
what it was created to do - to be the worldwide general audience means of transfering and storing of value.
