I pay sales taxes in other cities I travel in, I too should get a say in how they run their government. Money, after all, is the top virtue in a democracy; if it wasn't why did the founders ensure that slavers had equal representation?
"The Founders" of the US (however you want to form that category) were not the arbiters of what is virtuous about Democracy. Democracy is orthogonal to US law and intent. The PR for the US has always tried to message that they are a singular ethos.
My parents own two properties, but they have to decide which one they are residents of, because they are not entitled to a say in how both local governments are run.
If I am a long-term owner of Google stock, I still don't get a say in how Mountain View runs their city. A "vested financial interest" in an area should not be enough to give one a vote on local laws.
