Good. If you cannot afford the price of doing business illegally, close up shop or leave. And then you will be charged as foreign company when you try to sneak your way back into doing business in the country you left with the much more fun threat of being declared illegal and your products and/or services pulled from the market.

While you thought you presented an argument against hefty fines, you actually gave the perfect reason for why they should be hefty. If illegal practices are affordable, they're not illegal. They're just the price of doing business. So make them hurt.
