The median EB attack against BU explained. I’m looking for a technical defense.

Let's say 45{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} sets EB to 2MB, 30{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} to 4MB, and 25{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} to 8MB.

Now a malicious miner with 3{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} of the hash power (was signaling 8MB) mines a 3MB block. Assuming default AD 45{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} of the network fails to stop the block from inclusion and orphans 4 blocks. Now their "sticky gates" are hit and therefore completely open for 144 blocks…

Now the miner mines a 6MB block, which is immediately accepted by the 25{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} signaling for 8, as well as the 45{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} who no longer have a vote since their gates were hit. After 4 blocks it is integrated again…

Now again the attacker has created another ropportunity as a full 75{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} of the network hash rate will have their gates wide open. Now this attacker mines a 1GB block full of the most computationally intensive transactions and hashes he can manage. Let's be nice and say it takes a day to validate and download the block. The entire network grinds to a halt as it is automatically accepted by a 75{88c91daedd271a990a10650c05d769cae2765e0603edf30ca95f18704e5748e8} majority thanks to a single miner with just enough hash power to reasonably expect 2 or 3+ blocks out of every 144.

I want to hear a solid technical argument as to why this wont happen.
