In a nutshell:
A successful 51% attack will let the miners reverse payments and steal coins, but kill the trust in the network and crush bitcoin price. So the attackers gain nothing but a pile of worthless coins and useless hardware they cannot sell. And if they short shit ton of bitcoin before the attack they must be absolutely sure it works. This cannot be done stealthily, so others will see and have double motivation to thwart the attack, squeezing the shorts while saving the network and the value of their ASICs.
Powerful Nation State-
- prints money to execute 51 percent attack
- use printed money to short leveraged longs like MSTR
- control media narrative (quantum threats etc)
- simultaneously ban ownership, transactions, mining
- confiscate from treasuries
If COVID can take Bitcoin to four digits, I seriously think this could as well. Could even be net profitable.
The US could do this and no other country would give a shit (China and Russia aren't going to swoop in).

I would like them try. This will nuke their own currency first. How do you ban ownership, mining and transactions, exactly? There are other countries in the world besides the US. They will continue mining uncensored version, effectively forking the blockchain. The US will be left with coins that no one wants.

thanks! that's how I remember that explanation

I have often felt that the real risk of a 51% attack is control of the network. For instance, a miner with greater than 51% of the hash rate can attempt to reorg out blocks that include transactions it doesn't like.
We might say that this would wreck the value of the coin, but imagine it was to reorg out transactions that were from widely disfavored groups: a ransomware gang or a militant islamic group that had released a bioweapon. Less dramatically, do we believe the ETFs and exchanges and treasury companies will give a care if a single miner gains 51% of the hashrate and reorgs out blocks that include OFAC sanctioned transactions?
reply
It is either uncensorable and decentralized, or not Bitcoin. We have thousands of centrally controlled shitcoin blockchains that are worthless and useless.

what keeps bitcoin from following my above description?
my only answer is the fee market.
But that only works if people are willing to pay the fees. If people do not want to pay extra fees for transactions a censor wishes to exclude from blocks, bitcoin very likely ends up with miner centralization.
reply
I see the opposite: any shady transaction can get inside a block if the sender pays enough fee directly to the willing miner. Regulatory capture of the miners to follow OFAC rules, then sanctions against certain countries, then individuals based on social rating? That is certainly against the ethos of Bitcoin. I will stop using it immediately if that happens. And dump all my coins.
