In this scenario you would have access to due process. There are very specific rules when banks make decisions about credit worthiness, and for the part involving authorities you’d have access to a well developed legal system where you have rights.
Credit worthiness, yes, though that’s typically at approval time and not later on.
Risk bans or bans for suspicious / illegal activity? Totally different story (see the stories of Stripe / PayPal / etc shutting down accounts). The government (at least in the US) will punish banks pretty hard if they don’t crack down on fraud hard, so banks tend to lean more towards over enforcement.
Stripe and Paypal are not banks, last I saw. Which is exactly the reason they have to be so careful. They don’t have to adhere to the same rules as banks, but they don’t have the same protections either.
