> Fire safety is less onerous and less complex.

If there is one thing that is incredibly complex, it is fire codes - in no small part because these vary from town to town, or to be more precise, the height of their portable ladder trucks. Once you build higher than these, you have to plan for a second escape route.

That's not that bad of a thing if you work exclusively in one area... but good luck if you operate across the nation or, worse, internationally because everyone does things a liiiitle bit differently.
