New laws of physics can be hard to build awareness of.

For the system to be acceptable, people need to intuitively grok its physics and why it's safe.

This seems like an impossibly high standard; most people won't be able to grok the model.

But in practice it's not necessary

For example, when was the last time you thought about the same origin model, the fundamental security model that undergirds the web and apps?

In practice what you're looking for is not "will everyone understand it and therefore accept it."

You're looking instead for diffusion of awareness of the acceptability of the technically complex model.

You can do this via a chain of people vouching for it.

As long as "your more savvy friend is OK with it" is true, inductively back to the person who understands the system directly, then it's viable.
