Well, they're the same thing. Replace-by-fee *is* miner collusion in
knowingly mining a double spend, just triggered in a certain way.

Remember that you aren't paying the bad pool, the bad pool is paying you.
Whichever pool benefits from the scorched earth protocol can simply pick an
address out of the transaction it perceived as starting the protocol, and
pay that.

I think this is the core point which many of these debates revolve around.

No payment system provides *guarantees*, though some are stronger than
others. All they do is manage risk.
