No tie a rope to your feet and put a strain gauge on it.

When you are standing there according to you I have no force I just am. read the strain gauge it will be at zero I am not pulling.

Now I am going to pull on the string I can clearly see I am putting a force on the string THIS IS VERY DIFFERENT TO JUST STANDING.

What is opposing the new force I am applying you can see and measure it but it doesnt do anything there is nothing pushing my feet down I am allowed to have a one side force the strain gauge clearly shows I am applying a one sided force.

The only option I can see in your world you can have forces that don't do anything?????

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
