I see a lot of these type bags with straps around a painted tube so people evidently either don't care or haven't had any problems. But I've seen and experienced abrasion on painted seat posts from a seat bag strap. Wouldn't want that on my precious top tube paint.
When you put it that way, I might put a sock around the tube and the strap around the sock, so it’s not in direct contact with the frame.
