Sure but that's not the argument that the article made. Thats an important point to discuss and there may be ways to mitigate the damage of such a compromise (multiple curves, per key escrow). The article made a ridiculous argument for why backdooring is "impossible". Presumably they made it to persuade laypeople but what they really did is misinform laypeople and set them up to be pushed to the other side when they find they've been lied to. Not to mention you're also fucked if an unintentional flaw is discovered in AES or similar. You still need to be able to upgrade you crypto in response to advances in the state of the art, or leakage of important secrets.
