Quite.
TDO has talked about the need to write something clarifying the difference between, say, a raksha and Joe Mortal who walked into the wrong Wyld patch and had his thread obliterated.The most useful analogy I've found is that Fate = physics. Fate makes sure that heat isn't cold, that doors lead to the next room and that light gets hindered by solid objects. It's probably really unhealthy for people who cannot generate their own substitute for this (such as many Exalts can) to be outside Fate for too long.
...although note that almost everyone in the setting has a Fate-equivalent that keeps the world working as usual for them, even if they are technically outside of fate. The Underworld has the Calendar, Autochthonia has the Design, and Malfeas has Malfeas telling reality to sit down, shut the **** up, and work in a logical fashion.
