The hard part is getting used to it. How do I share my public keys? How do I use GPG (the program)? How do I access them easily? What do I do when I want to encrypt my mails on desktop (maybe Windows+Linux), laptop, and phone? It’s just relatively much work to gather the knowledge.
I’m so used to GPG, I no longer know which parts aren’t user friendly.

+ the fact there’re not many people using it
There are so many email clients, any email encryption system has an uphill battle to adoption. It’s easier to just build a new ecosystem.
