In a sense, I’d rather nurture and develop well behaved fans than developing a region full of photo-taking people at concerts. Letting the public do whatever they please isn’t going to help, either.

In America there’s no law like Japan on this exact issue, but concert management still can impose their own rules (obviously they’re allowed to as a part of the agreement allowing the attendee attending the show). People still sell concert DVDs and the like, and people don’t fret about censoring out people on their own cams on youtube, for bands who don’t care about selling DVDs.

The real open-minded artists, when they tour, they know different countries do things differently, and adopt. It’s not going to be the case all the time, especially for someone like May’n, who’s really just an idol being managed by an agency producing her. You are right to say that it might discourage some artists from doing shows overseas, but I don’t believe you can get around problems like this, in this day and age.
