You’re assuming the threat even exists in the first place. Your entire argument is built on assumptions you cannot verify.
Whatever it is that makes Bitcoin immune in the way you’re suggesting does not magically extend to Ethereum, because this isn’t about a specific chain, it’s about the architecture of time. Bitcoin doesn’t add immunity; it reveals the object you’re misunderstanding. You cannot perform the computation you assume you can because your model of time is wrong. Full stop.
There is nothing mystical about Bitcoin beyond cryptography enforcing conservation. What Bitcoin actually exposes is the error in the threat model itself. The assumed computation fails not because Bitcoin resists it, but because the computation presupposes a continuous-time substrate that does not exist.
