"the higher powered the reader is, the farther away it can read it... and crypto can be broken-- especially since it's limited by the relatively small space
available on an RF tag."
Well, the power of the reader has nothing to do with it. It's a radio signal. What you need is a powerful antenna. If you have a 70 foot antenna you might be able to capture the radio signal from afar but that would not be easy to hide. Current RFID chips can support up to 2K of data which is more than enough space for encryption.
Personally, I'd be more worried about the hackers than the government. Somebody already demonstrated back in '06 at Defcon in Las Vegas how to clone the RFID passports. I love it. I'm not a fan of RFID in passports but I'm not going to lose any sleep.
