You don't lose access all at once.
It fades.
A delay here. A manual review there. A withdrawal that suddenly needs "additional verification."
Nothing breaks. You just stop moving freely.
This isn't security. It's controlled access.
Every platform that holds your identity decides when you can act, what you can do, how long you wait. And you don't see the rules.
Sign is trying to flip that model. Proof instead of permission.
I'm not fully convinced yet. But I've seen enough to stop assuming access is guaranteed.
Access isn't a right in these systems. It's a condition.
Have you ever been slowed down by a system that was supposed to protect you?
