Oh, Draco is definitely scared of being left alone. What happens next chapter just makes it worse. (Cheerful, ain't I?)

But Harry thinks that a future living in the maze is no future at all. He wants Draco to have options. In his view, taking away one choice- to have Harry with him- is acceptable if it presents him with another bevy of choices.

I get what you're saying, no worries. And I think Harry may still be thinking of Draco as a victim, even though he's trying not to- and victims need to be sheltered and protected, sometimes even from themselves.
