It only requires a very short duration to send the difficulty permanently into the stratosphere. Only a fork can revert it. The attacker doesn't have any ongoing cost. The rental cost is cheap. All your CAPEX arguments fail because you forgot about renting.

Incorrect. This is mounting a 51% attack for approximately one day in order to double the blocktime for approximately two days. I do find it interesting though when people suggest attacks that are way more expensive than a 51% attack and have relatively insignificant impact.

Incorrect. This is mounting a 99.9% attack for a fraction of a years in order to increase the block period by 100X for a period of years.

Please get the math correct.

For how long do you want to keep up your 99.9% attack for? Like for how many blocks?
