I didn't say anything about gatekeeping. It's okay to make mistakes, that's one of the best way to learn.

I said if one isn't comfortable with the math, maybe don't try to roll one's own crypto and advertise or use it as production-grade crypto.

It's difficult to assess one's "comfort" with the math. I've been working with crypto for more then 10 years and I wouldn't say that I'm perfectly "comfortable" (e.g. the Ristretto stuff). Should I stop working with it?

You should not implement Ristretto, and continue implementing stuff that you're comfortable with.

Crypto is deep. You can get involved at the levels you feel comfortable with.
