Don’t do this. Not in America, and not in places with “consumer protection”.
Chargebacks are for fraudulent or erroneous charges, not for “you changed your mind about a purchase”
(1) first up in this case, I’m fairly sure that every other party to the transaction would have grounds to say that the chargeback is fraudulent. The author is not saying that they didn’t make the reservation, they’re saying they realized after entering a contract that the contract was not what they wanted. Similarly the “host” is not breaking the contract: the person agreed to these terms of the contract, apparently having not read them. So this is not a fraudulent transaction, and claiming it is (for a charge back) just sounds like fraud
(2) charge backs are not free to the merchant - as I understand it the merchant is subject to penalties from the processor and/or bank that can easily be hundreds of dollars. So even if the bank doesn’t take you to court for fraud, airbnb maybe unhappy at having to cough up a few hundred dollars.
(3) it seems like (IANAL) your chargeback could also be taken as a breach of contract by the host, and frankly they don’t seem like people who will take a no harm, no foul response to this, especially if they not only don’t get paid but if Airbnb offload any of the chargeback costs.
Fundamentally your running into the reason that there are regulations governing hotels and rental, and why Airbnb insists that in spite of all evidence that is not what they are providing.
