I don't see how it follows from the fact that the areas responsible for rough estimation are active during symbolic tasks that those areas are functional in symbolic reasoning. It may just be that we usually also form rough estimates whenever we're reasoning precisely with symbols. That is, the activation of the areas responsible for estimation may not actually be functioning as part of the brain process responsible for symbolic reasoning but rather are activated in parallel with the symbolic reasoning as part of a separate process. For example, young physics students are trained up to check their calculations for plausibility with all kinds of estimation exercises. Such exercises are standards of physics texts. It doesn't follow that estimation is somehow part of calculation from the fact that they form a habit of estimating whenever they calculate.

In my opinion the largest threat for California are cataclysms and ecological catastrophes. Not important is how many money we have because one tragedy can us take all.
