51% attack on bitcoin doesn't let you remove coins from someones wallet it allows you to change which transaction history is considered the real one. So you could send someone bitcoin then do a 51% attack to make the chain without that transaction longest so you get to keep your bitcoin but you can't use it to just take money out of someone elses wallet.

“You’ve got it all wrong officer, I wasn’t talking money from his wallet, I was changing history such that the money was transferred to my wallet instead.”

It's not about if one is wrong or not it's about what you can do with it. With a 51% attack you need to have a recent transaction to the wallet you want to attack and have received economic benefit from the transaction already.

It allows you do to a refund it doesn't allow you to take random bitcoins from a wallet.
