Earlier quoted context omitted.
I've yet to understand why 'land' should have a stronger vote than 'people'
Why even have states? Or cities? What purpose do they serve?
Why have states? Why indeed!
One answer: to create a level of governmental organization smaller than the federal one that can act as a set of laboratories for legislative and legal experimentation.
Another answer: to reflect the fact that not all laws and regulations make sense across a diverse range of climate and geography and demographics and economies.
Neither of those answers, however, require states to be considered inviolable sovereign entities, and a lot of us born after 1880 don't think of them that way.
