Catalog sales (paper) don't charge sales tax for out-of-State sales. Are you suggesting that they be taxed also? Why is the internet any different?
I personally do not have a detailed opinion on the matter because that requires a detailed study. However, a simple dismissal of any tax is wrong for the reasons I mentioned. It is also wrong --- and that was the motivation for my original post --- to be against that tax because we think that the tax burden is high.
In sum, I do no pretend to know what is completely "right," that is, best in this situation. But that does not preclude one to recognize some wrong arguments, does it?
