"I disagree. It's too expensive to run a low level brain sim."

Interesting. Could you tell me Why is it too expensive?

If it wasn't expensive, would that change things drastically, and make brain sim a viable option?

The brain has 10^14 synapses (100 trillion) synapses. Current day neural nets barely reach a hundred million, with very few exceptions. Then, besides compute, there is data movement - currently the bottleneck in AI is moving data around, not computing. Imagine the interconnect for a brain-size neural net.
