Yes, you can migrate to country with fewer rules and not operate on other markets. Like a brothel with underaged prostitutes that people from other countries travel to to buy services disallowed on their native markets.

In practice it doesn't work that great. Stronger countries with richer customers tend to use their leverage and have more rules. It definitely works for illegal products but I doubt it would work for goods that are legal but coming from manufacturer who's illegal. Goods would got cloned by legal manufacturers pretty quick if they were so good they'd be worth traveling for.
