I agree, but this is yet another example of the internet taking a good thing and twisting it until it's bad. People abused the system by selling games from cheap regions to other people from non-cheap regions. It's a common practice, look at the Steam sale thread. The same thing was going to happen with Steam sharing, people everywhere were dreaming of buying one copy and sharing it with ten people. That's abuse.
Maybe so, but then you fall into the issues publishers faced from adding intrusive DRM. You're punishing your average consumer trying to stop people who will find a way around it regardless. Be it now using keys instead with a VPN, or even just not paying at all and pirating it.
Instead they should be offering rewards or incentives for those paying more. Equivalent to what CD Project did trying to combat piracy, they offered neat little goodies with Witcher 2(Soundtrack, tips book, map, etc), and also did a CE which offered a lot of neat collectors item for a very good price. It was still pirated, but those are people who were never going to pay in the first place. What they got in return was a lot of happy customers who will be happy to pay for the next release.
Something like just offering the base game for cheap in Brazil/Eastern Europe, and then having a more expensive version(which could still be bought in Brazil/EE if they so wished) which everyone else gets, that contains small goodies. PDF of artwork/maps, soundtracks and so on.
