I have been wondering if it is possible to commit a copyright suicide by waiving all copyright for all my previous and future works by writing a statement -- possibly hand and digitally signed -- saying I apply CC0 to everything I ever create, then distributing it on multiple internet platforms including e.g. the Internet Archive so that it cannot be deleted. Why or whether I would actually do it is another topic, I am now just curious about whether it is possible. Does anyone see anything preventing me from doing this? Any interesting consequences?
Would this in theory e.g. cripple me in the sense that I wouldn't ever be able to be legally employed as a creator of copyright intellectual property? E.g. I wouldn't be able to paint art for a company creating proprietary games, since I wouldn't be able to transfer my copyright on the picture to the company since I wouldn't have any.
