With 'fully' I mean that command:
ssh target_machine_name date
gives the date without asking a password. The mere sending id_rsa.pub

That's odd. I am able to get commands to work over SSH without a password.
I copied the contents of ~/.ssh/id_rsa.pub on my work computer into
~/.ssh/authorized_keys on my home computer. Now I can SSH from my work
computer to my home computer like this:
ssh me@myhomepc date
And it logs into my home computer and then runs the date command. I did not
have to do anything with the authorized_keys file on my work computer to
make this happen.
That's all appropriate.
You only need to modify authorized_keys in both places if you want the
symmetric relationship that either machine can log into the other.
I mentioned that I did not have to alter the authorized_keys file on my
work PC in response to the OP's statement:

I have no idea why you would need to do something like that. I have
never had to "cross-append" anything in order to make this work. I just
wanted to clarify for the OP that the keys only need to be shared in one
direction to do this.
He seems to indicate that the passwordless login works just fine unless
he tries to run a command through the ssh command line. I don't know
why that would make a difference.
He also mentioned scp, and I think the better alternative would be to
run sftp with a batch file.
