> They can't be held outside Fidelity accounts, so what happens if you get caught up in some KYC nonsense and Fidelity closes your account?

This literally happened to me. I'm banned from Fidelity for some unknown (AML presumably) reason but have no other issues with any brokerage, bank, or exchange.

Fortunately I just held a bunch of ETFs, so it was straightforward. But it does happen.
