Sure the way to avoid damage deck shenanigans, is to have players exchange decks prior to a game starting.

I insist, stack your damage deck as much as possible.... *evil grin*

People do lose cards, so replacement decks would be a good thing.

and people can damage them , spill a soda on a table with cards on it even in sleeves and you have cards that are done for. or a cat chews some up because you were eating and got some greasy finger prints on the sleeves. or your loading the car and your tackle box falls off the bumper and lands in a puddle. your 3 year takes the cards off the table and cuts out the stars on the back to put in her scrap book. or just step on them. Really there are endless reasons to need replacement parts for games. Real game companies that care about their players sell replacement parts to their games. Hasbro, Milton Bradly, agents of gaming, Mayfair games,ETC ETC they all sell replacement parts. Its one of the ways they keep players happy and coming back for more. forcing them to buy a whole new game or into the after market is not the way to do business .
