>So why even copy the chain first he could just start asking for the hash of the whole thing and if they all have the same there is no point to copy the chain.

Well if I control enough nodes I can send you fake hashes (51% attack).

51% is actually a different attack.

The type of attack you are thinking of is called a Sybil Attack [1].

See other message. Listening to a nodes is voluntary and secret you dont know who or if at all anyone listens to your node. If you simply created a bunch you can be sure no one will listen to them. It doesn't matter how many % they make up.
