Well, the measure is just plain dumb... doesn't it limit using a game to just one console? It wouldn't just affect "used" games, it would prevent you from taking your games to your friends home... I guess they could do a login thing which would allow you that but that only works if you have an internet connection (which perhaps means they actually want you to be connected to the internet 24/7). while wifi is readily available in the US and Japan there are plenty other places where it is not necessarily as standard.
Polls are reality are not necessarily on par though. Once the PS4 or xbox 720 are out people will definitely have to consider whether the inconvenience of security measures are worth not getting the game.
Overall I don't think destroying the used game industry will actually be something which the companies have to concern over. As far as we know selling used games is not something over which developers or console makers profit from. They profit from selling to people who buy new games. Provided the measures don't affect those who buy new games regularly there is no reason for them to give a damn about people who buy used games or people who sell used games.
It's true the numbers in the polls are unlikely to be strictly accurate on who would actually refuse to buy a console with such measures, since a great exclusive launch game (or 100 other factors) could come out and change peoples minds. But polls like this one do give an accurate reflection of opinion on the issue.
If public opinion of a console is affected then it's very much something that should worry a console manufacturer.
I think it goes deeper than the annoyance and impracticality of a constant internet connection for most people or that it shuts down used games sales (which is a something lower income gamers use a lot of because they are cheaper) or that it also shuts down any possibility of game rental services (such as gamefly). While these issues do matter I think the biggest thing is that it's insulting to the consumer.
A console manufacturer is asking that people pay $300-$400, which is not an insignificant amount of money, for a console and then they turn around and treat gamers like a bunch of thieves.
If I went into a furniture place and bought a chair. And the sales person was like "Now your only allowed to put this in your house, your can never move it, never resell it; and we're putting a digital tag on it to be sure." I'd be like "@#$@ you @#$hole, I'm shopping across the street!"
