dkbit98 thank you for the feedback. Great question!
I wanted something to do peer-to-peer transactions.
The Bitcoin white paper's first sentence: "a purely peer-to-peer form of electronic cash".
If you use a hardware wallet or any other wallet that is not using your own node then you are doing a three party transaction. Any third party transaction is not permissionless nor is it free. There is always a cost to use a node someone else is hosting.
The Epiphany is Bitcoin as it was intended - peer-to-peer.
This may seem like a small thing but I contend that it is not small. It is the core of Bitcoin's purpose - Provide people with a way to exchange peer-to-peer without having to trust anyone. If we allow third parties in our transactions we are creating an electronic version of the banking system we already have.
The Epiphany is designed to appeal to people who want the freedom and sovereignty that Bitcoin can offer if used properly.
