As other have pointed out, this wasn't taken down by Bowie: it was taken down by the uploader as the result of the expiration of the original one-year license that Bowie agreed to. Essentially, Bowie allowed it to be uploaded in the first place, but only for one year. But I guess no good deed goes unpunished.
I didn't know youTube was a space-based service delivering content to people in space. If your argument was correct, piracy would be legal so long as the actual pirating/copying/infringing was done in a country with lax copyright laws.
WTF does "popularizing" a well-known song have to do with copyright and its function? Do you want to also argue that Bowie should pay Hadfield for his (unsolicited) advertising? Does popularizing a creative work have anything to do with copyright's stated purpose of encouraging creativity? Are creative artists only allowed to be concerned with how popular their work becomes?
Absurdist arguments, indeed.
