Oh boy, a bit of generalities being thrown around here. Chargebacks aren't automatic dismissals of a legitimate charge. Saying things like " If a customer disputes a charge for damages, the card issuer will not pay the merchant" really should say "if a customer disputes a charge for damages, the card issuer will investigate the charge and ask the merchant for proof of the charge being legitimate, if they send them proof such as a copy of a contract signed by the issuer, the credit card company will then honor the charge." Disputing a charge is only the course to a possible resolution, it isn't the resolution.
Again just your assumptions, number one, you don't know what the contract says for one thing, number two pre-authorizations are just a method to make the process simpler for the merchant and nothing more, they aren't a limitation on what can be charged. The merchant gets one to make it easy on themselves, again if it's disputed they send a copy of it to the credit card company "Here is a copy of the hard copy of the charge with the customers name on it". That just makes it easy for the merchant. If the contract says you're liable for the cost of the car and any loss of use, they don't need you to pre-sign a credit card slip for it in order for them to charge it, they simply charge it through electronically. If you dispute it again see the first paragraph of this reply. Also the amount pre-authorized here is the assumption it's for damages to the vehicle, most times this isn't the case, it's a blanket amount for 'additional charges' could be not filling with gas upon return and any manner of things, again it's just making it easy on the merchant to get paid, but it isn't setting a cap on the renter's liability.
The answers to the liability of the poster are on the rental contract he signed, and/or the rental agencies policies in regard to insurance waiving.
The renter may be "liable," but that doesn't mean the rental company is allowed to charge his credit card without his explicit pre-authorization. It's my understanding that pre-authorizations have to state an amount--they can't just leave it open-ended. It isn't like the car rental company can come up with a figure that they think makes them whole and just charge his card in that amount.
