The risk of fire and collapse is mitigated to a large degree already. People are arguing about the relative utility of further mitigations. At least in the US, folk mostly build interior walls with sheetrock and their exterior walls with cement based composites. Bedrooms are legally required to have smoke detectors. Electrical and gas runs are supposed to be installed "to code". Tall buildings require engineering to make appropriately strong structures. Buildings don't completely burn down or collapse very often, especially compared to the frequency of serious car crashes.
