Condensed the Flaws I See in Geographic Representation

I don’t completely understand geographic representation. Why are we giving so much credence to where people live? Most of us spend almost as much time where we work as where we live.

I don’t live, work, and shop entirely in SE Austin never crossing IH-35. I commute to NW Austin, I create theater in North East Austin, I visit my mom in South Central Austin, and I shop in South West Austin. Why is it more fair for me to have a huge say in the neighborhood where I own a home, and little say in other areas of town?

The municipal park 1/4 mile from my home has a skate park. Why does where my house is located mean that I’ll have more say over skateboarding related issues? I know NOTHING about skateboarding. That seems somewhat silly to me.
