I agree. I like this topic, but I have to say that there are better, more fundamental arguments in favour of 3 space dimensions. For example, two space dimensions only allow planar graphs, which seems pretty limiting for the development of complex structures. On the other hand, as you increase the number of spatial dimensions, the curse of dimensionality becomes more important and space in general becomes "emptier". Also, knots are only interesting in 3 dimensions. Arguing about time dimensions is harder, because time is tied more strongly to our subjective experience of consciousness, which is something that we really don't understand yet.
