The 4 million fine for the third smuggling attempt, is hard to reach actualy.
Most smugglers get caught a maximum of 2 times, then they are more cautious.
To land on the criminal list, you have to be a really valuable smuggler.
If you do the same smuggling route over and over again, still not avoiding the checkpoints, then nobody can help you anymore.
Smuggling is about roleplay, about staying hidden and using camoflague for your cargo.
Just running with your load is the proper roleplay for admitting that your cargo is full of illegal stuff, no matter what you tell or where you hide it.
And its about the Taxing system for certain goods in here.
I want to develop it if possible, so it makes the most sense.
