I agree, if people had more flexibility as to where to operate it would be less of a problem. This is mainly the fault with band planning (designed, as someone else said, in the days when the only digital mode was RTTY) but also due to the fact that frequencies for ROS operation were specified rather than allowing people to work wherever they find a clear spot. Although not the same issue as the legality of spread spectrum in the US it is the same kind of issue as I believe it is the case that you are not free to use digital modes outside the allocated digital sub bands whereas there is nothing to actually prevent anyone in the rest of the world from finding a quiet spot in the SSB sector to conduct their weak signal experiments using wide band modes as the band plans are only a "gentleman's agreement."
