If the regulatory agency decides to fine you, and you don't successfully defend yourself against that in court, then you'll have to pay that fine. If you fail to pay the fine on time, any entities within the juristiction that owe you can be ordered to pay the fine instead (i.e., your payment processor will be ordered to redirect funds arriving for you to the state, which also, as far as their juristiction is concerned, fulfills their debt towards you--as far as their legal system is concerned, the payment processor has paid you and you have paid the fine).
Except that won't help you? Usually, payment processors are ordered to redirect funds as that is usually the easiest way, but if that is not an option, your customers will be ordered directly to redirect payments. As long as you have customers within the jurisdiction, they will find a way to make you not earn any money from them until your fine is paid.
