I doubt that reasoning.

15 years ago $250,000 could crack a 56-bit key in about a day.
After 10 Moore's law cycles that's 66 bits today.
1024-bit RSA may be worth about 80 bits of symmetric key.

If that's so some tradeoff between budget and time almost certainly
brings keys of this size into range for cracking - e.g. spend $250M
and crack a key every 16 days.

One remailer private key reveals many messages.
