Earlier quoted context omitted.
No, it doesn't make sense that people should have greater voting power based on their location in the same polity. Your argument is equally valid in reverse -- there's no reason why rural dwellers should decide what happens in cities. Why should your vote count for more because I have more neighbors than you do?
While city dwellers vote may be technically less powerful on a per capita basis, they make up for it in numbers. There are simply more of you with similar needs/wants. Not to mention far more money to achieve those needs and wants. In a city an individual's needs from his/her government are just less unique.
So...rural snowflake status confirmed?
