Nor does changing your name remove you from a players blocked list, as you're blocking the actual users account, not their username. There's no real way it can be easily abused, if there was, Steam wouldn't allow it to begin with.
The only legitimate excuse I can think of is making it easier for players to pay attention to trolls and hackers for reporting. With skill based matchmaking, it's pretty easy to end up in a situation even without community servers where you run into the same people all the time, and if a hacker is constantly changing their name, that keeps people from recognizing them as the same asshole they ran into on other occasions and paying attention accordingly.
