Who says it's going to be encrypted? The service provider may screw up in more ways than one...
The data that may be plausibly stolen from me alone doesn't have a lot of impact if I'm the only victim. It starts to matter a lot more if it's stolen as a part of a larger heist. Eg. if someone knows I'm saving money to buy a particular brand of car, then it doesn't matter really, but if someone knows that among a million people 3KK want to buy that particular make, they may have a valuable insight about making investments into car manufacturing industry. Of course this isn't limited to cars and investments. Suppose, someone stealing data discovers a trend in health problems which would increase demand for a certain drug... same idea.
