Many of us do work and are taxed in more than 5 states in a year.
Also, Turbo Tax software only limits the individual to 3 state e-files. When filing for other family members it allowed me to e file in other states that were different from the 3 states I personally e-filed in, therefore it does not stop someone from misusing Turbo Tax as you described. So in my case it costs Intuit revenue and makes me have to go to the post office like an "animal." :(
