My concern is not that they couldn't figure out a way to enforce this but that in the process of enforcement they would eliminate all "illegitimate" vendors and possibly eliminate my ability to buy anonymously.
"Illegitimate" for the purpose this discussion is a business/vendor that doesn't collect the sales tax when it sells a new retail item to an end user/consumer and/or give that tax to the government. It's up to each business/vendor to decide whether or not they want to violate NRST laws. A business/vendor could eliminate it's own business by breaking the NRST laws. Your anonymity as a consumer/purchaser is greater with the NRST.
What businesses/vendors do you think would eliminate their own business by violating NRST laws?
How would they be eliminated? I have given numerous examples in this thread of how sales tax is circumvented now and there is a lot incentive at 4.5% than there will be at 20 or 30%. Enforcement will only work if:
1. All businesses report gross sales honestly, or
2. All consumers report all transactions, or
3. All items are tracked from import or manufacture.
I keep hearing that #1 will be enforced, but not how. See my posts #637 and #642. The flea market is a crude example of more sophisticated black markets that will arise from a high sales tax. I believe that it is inevitable that the government will mix in enforcement mechanisms 2 or 3 above, which although still unworkable, will end purchase privacy.
