I don't really have a reason to be against it, but I would have absolutely no reason to change it from normal.
Honestly, I think difficulty should deal with needs. They used to be kind of insane. In the original Sims, you had to have a high cooking skill if you didn't want to eat all the time. In 1 and 2 you genuinely struggled to meet their needs.
You also didn't really mention death increases. The older games could kill you off pretty easily. I would expect to see more death in a more difficult setting and less in an easy setting.
