Why do I need to create another subkey when GPG creates a default subkey

Why do you need to create another subkey when gpg by default creates a subkey? Couldn't you use that subkey and set an empty password?

Is it because that subkey is encryption only and we need a subkey that supports decryption too? But then why select option 6:

Please select what kind of key you want:
(3) DSA (sign only)
(4) RSA (sign only)
(5) Elgamal (encrypt only)
(6) RSA (encrypt only)

For a key that is encrypt only?

I confess that the reason for this decision was that "it worked". I tried a few other things that didn't work and this was the first one that did work. Maybe I didn't see the default subkey? (I don't know, I didn't keep notes about that).

I'm not a crypto expert, just a GPG user. I'd be glad to change the process if you find something that works better.

Yeah I just wanted to open up a discussion about it. Maybe someone who uses GPG a lot more and understands the output will chime in.
