First: you can probably be observed using them. Unless too many people use mix networks you might just end up attracting unwanted attention: more passive surveillance, maybe even active attacks (at the limit very physical attacks). Second: I suspect that to be most effective the mix network also has to be most inconvenient (high latency, for example). That probably means mix networks won't be popular enough to help with the first problem. Third: the mix network had better cross multiple jurisdictions that are not accustomed to cooperating with each other. This seems very difficult to arrange. I'd love to be disabused of the above though.
