In all research done on this subject there were two principles that were demanded by consumers, private industry, and government—uniformity and non-duplicity. The very fact that 50 states could enact 50 different tax policies with 50 different definitions of nexus violates both of these tenets. It is quite likely that a consumer living in California purchasing a good in Nevada with a server based in Texas might have to pay taxes on three different occasions. States would enact policies that maximized their advantages.
