" but regardless im not interested in the issue of chargebacks I just want to know if theres anything available for letting people sell BTC's."
Same reason there isn't a wordpress plugin which allows you to randomly corrupt files on your webserver or a plugin which will randomly punch the operator in the nuts. There isn't much of a market in building things which ruin the user.
Your belief that the legal process will protect you in the event of a chargeback is horribly naive. The person making the chargeback doesn't have to PROVE anything. You have to prove the customer's claim is wrong and prove to the standard accepted by the credit card issuer. Note the credit card issuer, meaning the customer is THEIR customer. You honestly think credit card companies care that you claim to have lost digital monopoly tokens. The chargeback process is a rubber stamp. Your chances of winning a dispute involving digital goods are roughly 0%.
Can you sell BTC using reversible funding methods like CC? Sure. But it is very very risky and it can't be made easy enough for anyone without skill to do it via a plugin. That is just a recipe for disaster. The fact that you want to ignore this huge risk likely means the lack of a plugin will end up saving you lots of money.
