I think bitcoin has traveled past the point of getting a 51% attack on the network some time ago. The costs and just the ability to build enough computers to brute attack the bitcoin network is long gone. And any current miner knows that it is makes more economic sense to mine, instead of attacking. Look at smaller chains like BCH, there is easily enough hashing power available to 51% attack it, yet it is not. It would cost too much in lost profits to do it. Although on really small chains like bitcoin gold, the hashrate is small enough that it could be worth it to attack.

Agreed, original Bitcoin has so many mining worldwide it would be impossible (or stupid) to outlay for an attack on this coin.
The thought behind this is sound considering governments wishing to have their own blockchain facilities, who will mine them, who will support them?
Those wishing to attack, this indicates approximate cost involved for all to ponder before making such a decision (wise or stupid) https://www.crypto51.app/
