At the end of the day, all he needs to do is use the Satoshi key on a transaction on the bitcoin blockchain to prove everything. He hasn’t and can’t. Am I wro

  See the court records, he claims he can't do it because he distributed the key parts or something. Since it is hard to prove that someone cannot do something, yes, technically you are wrong.

  We're going to see such things at some point, there are a few "bitcoin address collider", some of them are even distributed.

    AFAIK, there are 160 bits of entropy in a bitcoin address. Let's say satoshi has ~1 million addresses with bitcoin in them (2^20). That means 2^140 attempts need to be made to steal any of satoshi's bitcoins. Cracking 128 bits of entropy is essentially impossible[1], cracking 140 bits is even harder. This collider tried 7 quadrillion addresses in 1 year[2]. That's 2^53, nowhere near 2^140.
