The paper appears superficially plausible, but the general heuristic that any mention of a one-time-pad is a strong indicator of crackpottery applies here.  AFAICT on a cursory reading, the paper isn't wrong, it just leaves out one teensy little detail: key exchange.  There is a reason that OTP is never used in practice despite being information-theoretically secure.

Criticality is always valuable, but we should also keep the door open to unconventional ideas, even if something appears impractical. If someone is misguided, it’s great to opine and share, as you have, but let’s not dismiss or gatekeep. While this may not fit with any of your uses cases, said cases exist. With proper engagement, who knows what could be created or verified therefrom.

This is ad hominem and unnecessary. Not sure why someone’s government-name must be used versus using a pseudonym. "Privacy is the power to selectively reveal oneself to the world” — Eric Hughes, A Cypherpunk’s Manifesto.
