What if people in china would rob some farmers. The farmers would be forced to work at slave wage or just for food at local factory. It would make new abibas boots from there cost x100 lower then you pay in normal shop. Someone would import them to your country, and you would buy them at x5 lower price at local baazar and then open up a shop.

No wait, not baazar.

You would buy it at most respectable and biggest imported good distributor in your Bitcoinville country.

Later police comes in and takes all your goods. Happy?

Again - I am not saying here necessarily that say mtgox is bad for doing the rollback or anything; Just trying to look at legal-moral problems that arise with trades triggered initially by some wrong doing; How should they reverse, who should refund which trader.
