My point was more that in the modern world people's interests likely cover a span or several spans of regions. Not just one single locality. Sometimes (near state lines in the US) not even /state/ level laws would provide adequate representational coverage. A more accurate way of providing representation might be to identify areas of major expenditure. Employment, Education, Living, etc. Aside from residency should be either by some absolute threshold of transaction value or possibly by percentage of income. A significant economic interest in an area should be related to representation in that area (as you are being taxed for your activity there). Corridors that connect those areas should also apply (you do have to traverse them for your interests); transit and transit related laws should thus probably be at a major metro or higher level.
