And I bet the NSA would break your homegrown RSA built with your basic understanding of group theory in a few minutes. RSA is extremely subtle to implement correctly and if you get it wrong you can easily leak everything.

It's not like I'm going to suffer from the ECB penguin issue: MY MSGZ R SMOL and my key size is large enough to avoid that. RSA really is very simple group theory. It was independently invented at least three times, as I recall.
