Will it be easier to stake a plant than to bag another? I've never done either, I was just coming at the argument from a different angle. How long are your stakes and how many per plant? I'm just trying to learn from last years Grow Blogs.
It will probably be easier for me to stake, I'm going to have to bend some of the plants over to bag, or get someone else to do it. How far can you bend a plant over to bag before it snaps? Holding my arm straight up, it's 6 ft. from the ground to the tip of my birdie finger seated in my chair.
Staking: When plants blow down, they usually pivot at the ground, either lifting out the root ball, or snapping some roots on one or all sides. I've done stakes full height and half height. What seems to determine a successful staking is adequate length pushed INTO the ground, regardless of the above ground height. Actually, I had the impression that the staking was more stable if the top of the plant could bend in the wind without it trying to bend the stake as well.
Bagging or Topping
Your question about reaching to bag a plant from your chair raises some interesting challenges. First of all, as you well know, you can't get much work accomplished directly overhead, at the tip of your finger. The objects to be manipulated need to be lower than that. If we take 5'6" as a productive working height (for twisting, tying, inserting lightweight things), you should have a good chance at bagging at the button stage on the varieties (all medium size plants) that I was able to extract from the (currently) 9 pages of your grow log: Burley, VA gold, Izmir, Samsun-Maden and YTB. I should mention that my Smyrna #9 (an Izmir variety), in 2011, required a step ladder for bagging. And if you wait to a later stage to bag, then it will require some bending and be a nuisance. The tops of some varieties are fairly floppy and flexible, while others are stiff, and will snap off.
An alternative would be to plant just your seed producers near a porch or deck with a ramp, and not worry about them having ideal conditions for leaf yield.
If you want to venture into the frontiers of invention, then a long handled gadget that would spread a blossom bag at 4 corners, then release the bag, might allow you to bag any height plant from your chair. I'm thinking on the order of the banding tool often used to castrate livestock,

...but with four 30" vertical posts to spread the bag. While ties can be simple fabric or string, a Velcro cable tie might make it easier at at extended reach:
