The different CEXs would have to coordinate such price swinging. When the price swings in a direction on one exchange, arbitrage bots will put a pressure on the price to converge back with the other exchanges.

It'll get really expensive, and you'll be paying a lot to the arbitragers

No they wouldn't.

All they would have to do is "loan" tethers to their "whale" friends with the understanding that they will invest it in bitcoin and hold until they are told to sell. See article from wsj referenced below.

Exchanges don't pay arbitragers anything. People who sell their crypto too cheap do.
