I’m not an engineer/have no formal training in this area. My hunch is that your statement is perhaps true at a scale of a house. For large builds like sky scrapers you’re definitely able to include fire resistant and earthquake resistance features. I think ultimately it comes down to cost. It’s possible to get treated lumber that is fire resistant, but it’s going to cost much more than traditional lumber
