Depends on what you mean by "the whole of physics".

Good question. When physics is inferred from observation, there is no conceptual mean to distinguish physics from geography, except for a fuzzy level of generality. But UDA explains where the observation and observable comes from, and physics can be defined as what is invariant for all the observer. If the material hypostases did collapse, it would have mean that physics, as such would be empty, and that all observable truth would be geographical.

But it seems that everything theories and the string theory landscape and Tegmark's all of mathematics threaten to do exactly that - make of all of physics geographical, an accident of where you find yourself with the anthropic principle as the all-purpose explanation.
