The RFID being gone doesn’t “present a problem” that would prevent you from traveling.
But their presence makes Customs able to tell much more easily that the passport isn’t a counterfeit; the RFID chip in them isn’t just blindly transmitting your information in plaintext; it’s encrypted and there’s a per-session key exchange roughly equivalent in basic design to WPA wireless encryption, and the chips also have a hardware RNG to prevent guessing the next key. (See here for more details.)
In other words, it’s an authentication mechanism, no more, no less. (Which means its purpose is to raise the opportunity cost of passport counterfeiting.)
