There’s no need for withdrawals right off the bat. Many if not most who invest with fidelity aren’t concerned with being their own bank. It’s a different mindset. People with these firms also aren’t cashing out after they see some gains after a few years. It’s 30+ years grinding away through every cycle. Some are more savvy than others as it will always be and I am generalizing.

I'd be very surprised. But they are probably better insured than at FTX or so 😂😂
