It is not a matter of hypothesis but reason. At bottom are these two statements related to causation:

In the absence of time, events cannot occur.

In the absence of space, things cannot exist.

Space and time (dimensions) are both required for all physical causation including broken symmetry, brane collisions, etc. Energy and matter cannot exist in the absence of space/time.

Oh yes, I'm agreeing.

The symmetry view is that if everything is the same, perfect formless, there is no cause.. and your points apply here.

The view is, from a point of view of physics, a break occurred in this symmetry.. a point unlike all the others, which brought forth a difference-in charge let's say. This began the cascade of reactions, force/cause, result/change, force... cause arose due to there being a break in formless symmetry. This results in cause and effect, space and time. As you describe.

So rather than space/time expanding from big bang, it can be viewed as broken symmetry cascading out, like cracks in an ice pond.
