What's Wrong With Density Near a Transit Station?

I am glad we have triggered a lively discussion about development and the future of Fairfax County. Please remember that I am only trying to convene a discussion, not take sides.
Here's a question for today, stemming from the post by Charlie of Hunter Mill who said, "I believe that [Fairfax Supervisor Catherine] Hudgins is out to support the Wiehle Metro station by creating density."
If I read this right, Charlie believes that density is a bad thing near a transit station. My question is, what is wrong with density near a transit station? A case could be made that we want as many fare-paying subway riders as we can get so we don't have to spend as much of our tax dollars subsidizing Metro.
