It's certantly not the first time that I've posted about something technical where some altcoin then popped up with it as a sales feature on its whitepaper without even bothering to implement it. :-/
The funny thing is that CoinJoin's primary advantage is the network support for it is already part of Bitcoin since day one. Maybe it's not /completely/ pointless to launch a new cryptocurrency around CoinJoin simply because a commitment from a lot of users to use it might increase the anonymity set... but as far as I can it's nearly completely pointless (esp since in Bitcoin some ordinary transactions look like CJs).
If you're going to do something incompatible at the protocol much better can be done— as shown in practice by Bytecoin, or in theory in ZeroCash and ZeroCoin. ... even there isn't not a requirement to start up a whole new currency for it, but at least not pointless. CoinJoin isn't the be all end all of transaction privacy, but at least you don't have to switch currencies or convince people to deploy improvements to Bitcoin in order to make use of it. :)
