The trouble is you have both of those things happening together, and as far as I can tell, we simply don't know enough about the reproductive cycle of the Brazillian species. Coupled with the fact that the smaller the population gets, the more prone the seeds become to insect attack. As long as it's implemented properly, sensibly, and fairly, I don't have a problem with it. I do see it becoming a serious issue for musicians, collectors, and manufacturers, if it leads to a situation where there is a perception that instruments made for export, out of the U.S. market, are considered inferior. As it stands, you can still export, and musicians can still travel internationally (with) instruments incorporating Rosewood, but you must have the correct documentation, and certificates. There is sure to be a black market in both instruments, and counterfeit certificates.
