[Iwo Jima]

How do you know that the goods being sold on the street aren't used? Let's say you took a new DVD player out of the box and put it back in. Is is "used" now? How about if you play it one time?

You want to throw these people in jail and take away their homes? How are you any different from the existing tax masters at the IRS?

You should consider the ramifications of a governmental edict making a used item more valuable than a new one.

Where did the DVD player in your example come from? Is the manufacturer on the street selling DVD's?
