Yes, I'm not even having that plans on my mind to own steemit coin. I have others I'm looking up to with potential. After steemit-blog offered me amount which isn't up to 1 cent for 2 weeks that's when my interest lost for them.But you should care about your passphrase because it is not only for the steemit blog that you will need it for. If you are also interested in owning a steem coin. You will need the passphrase also to access your fund. But if you still insist on not having the passphrase, it is your choice.
