That's not exactly true. It's a non-trivial but not exactly difficult task to design a fair shuffling cryptographic protocol that every participant can validate after the fact.

On the other hand, that still doesn't prevent cheating in the form of the server providing information to some participants via a different channel. There's nothing cryptography can say about out-of-band communications.

So maybe fair shuffling is cute but ultimately pointless.

My point wasn't that a fair, auditable system couldn't be built. Only that we don't have that today, and I'd add that online casinos are incentivized to not build that.
