I suggested using standardized (or non-standardized, but other than OTP) encryption algorithms for an initial key data distribution channel that completely differs from the main communication channel and exists for a relatively short period of time. That's my key point.

I'm not going to dive deep into the topic of why I consider "just using standardized crypto" unsafe and prefer rolling another custom end-to-end encryption layer on top of it.

I'm sorry that you can't see beyond the algorithms. We're far ahead of the time when OTP was the only active instrument (aside from straddling checkerboards and Enigmas). Modern crypto can be combined in such a way that every encryption scheme finds its natural place. I honestly don't see why OTP cannot have one.
