And you find that sort of rootless existence appealing, do you?

Ruth: And you find that sort of rootless existence appealing, do you?
Jack: Well, yes, ma'am, I do. (My bold.)

Can I use "don't you" instead of "do you" in the above dialog?

If she had used "don't you?" she would have said it in an entirely different way. You do understand that, don't you?

I'm surprised (or even shocked)/I can't believe that you find that sort of rootless existence appealing. What's your response?

Ruth: And you find that sort of rootless existence appealing, don't you?

I'm almost certain/I presume that you find that sort of rootless existence appealing. Can you confirm?

Do you see the difference?

She's using do you? to create a patronising and challenging tone.

I didn't understand that until I read teechar's reply.

Yes, I do. Thank you so very much.

Notice the tone she uses. She is expressing disapproval.
