> Nodes even define the PoW algorithm that miners have to employ.

Nodes change PoW algorithm and the old miners have expensive loud space heaters. They know this, which is why they didn't follow through on 2x. They knew that threatening that attack leads to one outcome : ruin.

It's a complex subject, sure. But I can't force you to understand how bitcoin works dude.

In spite of your condescension, I don't think you understand what a 51% attack is. You are confusing agreement on hard-forks with POW consensus in your defense of why Bitcoin is not vulnerable to a state mandated 51% attack from China.

Satoshi's brilliant solution to the Byzantine generals problem of consensus is proof of work, not "nodes decide what code to run" precisely because nodes are vulnerable to sybil attacks.

-How would these nodes know that the 51% attack history is bad?

-A proof of work change is a hard fork, and these take months to deploy properly according to core.

You have no idea what you're talking about.
