I am not sure I understand your theories correctly. From what I think understand, I would agree with some parts and disagree with other parts. Even more importantly, I think this line of reasoning might end up limiting your understanding.
First, in my view, "yielding" and "empty/full" are different concepts that should be kept separate. To understand "yielding," I think you have to study "using soft to overcome hard" and "using soft and hard together" as well as "sticking," "adhering," "linking," and "following." When I think of these things, I think of them in terms of "strategy," "tactics," and "technique." A great deal could be said about each of these.
As for "empty/full," I think one has to have a good grasp of what exactly the relationship is between Yin and Yang and what exactly the philosophical term "Taiji" means. "Empty/full" or "substantial/insubstantial" are concepts that can apply to everything, not just Taijiquan, and not just to the trajectory of a push and a neutralization.
I believe Yang Chengfu wrote that "Distinguishing full and empty" (fen xu shi) is the number one rule in Taijiquan. This did not mean that much to me until I began to study Push Hands more systematically. What I think I now understand is much easier to show with applications than to discuss in words.
To me "distinguish full and empty" means that
(1) I must understand full and empty in myself,
(2) I must use full and empty in myself,
(3) I must perceive full and empty in my opponent,
(4) I must use full and empty in my opponent, and
(5) I must hide my own full and empty from my opponent.
Full and empty applies not only to the whole, but to each of the parts.
If you know the full and empty in your opponent, you may be able to attack his Jin using any of four different tactics: making them locally too full, too empty, not full enough, or not empty enough. You may also be able to make your opponent unable to separate full and empty and thus unable to make his Jin flow toward you. He will have strength, but feel unable to use it.
As you understand more, you can apply these concepts to the opponent's mind intent, Qi, and spirit, since all of these are connected with Jin.
If you have no one to do Push Hands with, you have two choices: prepare a strategy to do find someone to push with or find a way to incorporate some of these concepts into the form. In my view, the former is far, far better than the first, and there are probably more possibilities than you might think. If you want some ideas, let me know.
As for putting Push Hands concepts into the form, it works best if you have some Push Hands experience, but is still possible to a limited degree without such experience.
In doing the form, I think that empty/full is a very important concept in terms of weight and weight shifts, but is also important in terms of the transfer of energy from the legs to the torso and arms. It is easy to do the form with more or less correct weight shifts, but still move in such a way as not to really use the power the legs generate. This is often less a matter of skill than of understanding and intent/purpose.
An example might be the middle of Push in the form. As the weight begins to move forward, the energy needs to flow from the legs to the torso and only then out through the hands. Another example might be Repulse Monkey. In that posture, the pull must come first from the legs, and only then from the arms.

I cannot see how anyone could deny that Taijiquan has striking. How could such a person explain all the punches and kicks in the traditional form?

<font face="Verdana, Arial" size="2">I dont know how to train my ability to stay relaxed. I have no partner to do push hands with becuase I have no money for classes. My problem with push hands is that I use to much physical force, and my sifu told me to use the jing from inside, so In order to train I had to invent a way to measure the amount of jing I used with out flexing.</font>
In my experience, I have come across three different concepts that people use to mean "relax." The only time I was able to make rapid progress was when I finally understood the difference and chose one that worked for me. The concept I ended up with is
in some ways almost the opposite of what I originally understood and quite different than anything I had experienced before in other sports or martial arts.
I agree with the need to use "jing from inside"; however, if you practice the way the Association teaches, I would discourage worrying about using "physical force" in training the form or proceeding to "measure the amount of jing [you] use without flexing." Focusing on these things will probably not help you learn to "relax" in the way the Association teaches. If you are interested in this approach, let me know and I can post more.
Overall, it seems from your video clips that you have established an excellent foundation, but are at the point where it will be hard to make progress without a very clear idea about certain principles.
