I bet you are one of those people who insist that companies making under 1mil ARR should support multiple auxiliary payment providers in the event you get your funds frozen by the Stripe/PayPal. The infrastructure providers need to do better, the burden should not be on small businesses to account for the cost of black swan structural failures. Words are cheap when you only work for well capitalized large corporations because your personal check book is rarely impacted aside from short term unemployment.
The burden is not on small businesses. Most small businesses don't just have well over a quarter million dollars in cash just lying around collecting dust. And the few that do can open an account at second bank. It's not rocket surgery.
Beyond that, if they have the kind of cash flow where they need millions in cash sitting around, they should hire a finance professional. For many, many reasons, bank failure risk being a very small part of it.
