I guess you are advocating for security by obscurity here (security in this case being the security of the backdoor). Not so good. But here's an alternative. The government can mandate that each time you send an encrypted message, you send another encrypted copy. The first one uses your addressee's public key, the latter the NSA's public key. It's not particularly elegant, but it does the job. It's not 99% secure, it's 100% secure.
