If the government's of the world decided to destroy all machinery, studios, printing presses, and computers How is anyone going to get a hold of all the music? I think if the government did all that they would just want to kill us all slowly and get rid of music all together.
Besides, if they destroyed all guns, there would still be folkz manufacturing guns. How is Music any different. People would still keep making hiphop, only now it'd be on the downlow and it would be even harder to get seeing as the people making the music in there illegal studios wouldn't just tell anyone about it for fear of the government coming in and taking there studio away. It's impossible.
