I think you might be practicing a bit of Death Of The Author here because, while your interpretation is interesting, as you yourself acknowledge, you're reading things into it that aren't the creator's intentional message. For all we know, Eminem has a perfectly healthy relationship with his daughter, or as much as he can manage with his schedule and commitments, and just doesn't want to bring her into the business before she's ready, before she wants to, etc. And it's not a guarantee for success or happiness either. Hulk Hogan was never able to do much for his daughter despite actually trying what you suggest at least several times. According to death of the author, I could just as easily argue that all he's doing in his lyrics is representing people who actually are in the metaphoric (and fictional) boat with him. If nothing else, it's pretty unrealistic to expect Eminem to see that video at all unless he's a closet furry, and even more unrealistic to expect him to leap to the same conclusion you did.
