After the huge expense of processing all that data and matching it up against tax returns and going after the "scofflaws" (not to mention the cost of this lawsuit) would the state even come out ahead?

Most probably Yes - they might end up collecting tax for the past 7 years plus penalties plus all other major online stores that will be targeted once they win with amazon, plus all the taxes for all future purchases.

If national online sales get hurt, will tax invaders now buy overseas? ;)
