You do not need to obey the laws set down by the houses. In your case, you can blockade run between Liberty and Rheinland (and back again...) if you wish, but if you get caught, make sure you have a contingency plan. I shouldn't be saying that as one of the people who wrote that list of embargo laws, but... well, I'll be on your case if I catch you.
However, your attitude is something quite rare around here these days, so I hope you flourish here, Risiko. This place is notoriously unfriendly to new people, so I hope you manage to weather the storm.
