Quite right. A large part of academic respectability is to be cited. That's how the scientific journals tout themselves--with their high rankings in the Science Citation Index. It's also a large part of Google's ranking algorithm. If I use different names for different purposes, my stuff won't be identifiable as uniformly often cited, so I won't have a good reputation. I'll be considered less than perfectly reliable.

It's a system.
