Does all NMD have an undersized bare ground?

IT's Loomex or romex Shockdoc

But yes.

Yes if purchased as a stock item......but not necessarily.

You can order loomex with a full sized ground if necessary. I had it spec'd on a wooden construction building and had no problem getting it.

I can't see tie wrapping the loomex to the hangers as acceptable. Tie wraps are seen as a method of securing, not support (and that's a code interpretation for NMD...). I'm not following this completely but can you shoot some wood onto the beam so you can staple or strap? Might be okay, I don't know.

Yes it is a code interpretation. Inspectors in my area would completely lose their minds if they saw us supporting any wiring of any type with nylon ty-wraps. They will instantly fail the install.

You can do it but the ty-wraps must be non-combustible type.
