- Non-segwit transactions require 51% of the hashpower and a private key to steal. Segwit transactions just require 51% of the hashpower.

You statement is very confusing since you are taking about two things: a) 51% attack and b) stealing coins.
How can you steal coins without private keys on Bitcoin? What kind of bull shit is this?
Please enlighten me!

In big blocker world you dont need non mining nodes. Miners enforce and determine consensus. Therefore 51% attack can do anything they like including stealing coins without keys.

And with bitcoin the nodes wouldn't validate these transactions since they don't have signatures, hence this would result to a hard fork of the chain. And the miners could do a hardfork right now if they wanted. And they haven't yet for good reasons.

And what is most important: Exchanges do run their own nodes and would not accept the tx's stealing segwit from the rogue fork no matter if it temporarily have more hashrate than the original blockchain. Good luck doing anything with your worthless stolen "bitcoins".
